7×11×13=1001.
That's why you can take ABC, do the trick and get ABCABC, then doing again with a small enough number will result in ABCXYZABC where XYZ as a 3 digit number is ABC × 2
I'm glad somebody did the work lol
Genious 🤯
Wow
At least someone is good at maths
"I did the math" guy
7x11x13=1001
So if you multiply by it you get 1000 times the number (which is the same nember with three zeros) plus the number itself (which replaces the zeros)
That's clever
No clever at all, or at least more clever than you because we can do a lot of combination to have 1001. He tricked you and definitely clever than you but only YOU, not me.

It's a clever trick to show to kids for example. Doesn't mean you eed to be a genius to understand it.
@@fleursdelilas9487 agree, it's clever to show to kids who said "That's clever".

Sure, Ramanujan
@@fleursdelilas9487 sure, kid
I remember getting asked this at a maths challenge in primary school. Except we decided it would be easier to multiply the 3 primes together first, ruining the entire trick
No it won't
@@Monkey_Luffy01 yeah it did be the whole point was finding out how it works
@@Marl3421 isn’t it already pretty obvious?
@@eternxlhaaris5811 yes but it ruins the fun of the trick
Underrated content fr some of the most interesting things I see.
Love your vids. Keep em coming!!!
You are opening my mind. Please never stop! I love learning and this is amazing
He is multiplying by 7, 11, and 13, which is the same as multiplying by 1001. That basically takes the number, shifts it over 3 digits, and adds the number back again, making it repeat.
Try multiplying with 73 and 137. It should work with 4 digit numbers. 🤯
because that's multiplying it with 10001
it will work when u multiplying by any factors of 10001 (for 4 digits) and 1001 (for 3 digits)
@@random20000 🤫
Do it with 101 × 3541 × 27961, should work with 9 digits
@@xaigamer3129Nope...it works with 10 digit numbers actually
Here is another amazing trick:
Take a 3 digits number, any number, and multiple it by 1001. Look at the result...
Isn't it AMAZING??😂
appreciate the cool math and move on
@@_apsis🤣 u guys multiplying two numbers and calling it cool😭😭😭
When performing arithmetic ALWAYS wear a lab coat.
Me looking at his window the whole time: 👁👄👁
I did 891 and for the last number it said 892,782,981 😱
7•11•13 = 1001
So when you multiply your 3 digit number the 1 makes up XYZ,345 and the 1000 boosts that original number up to 345,XYZ. Put together (1000+1)345 you get 345,345
7*11*13 = 1001
1001*a = 1000a + a
Chosing any random three digit integer for a would result in having that theee digit number: abc times 1000 = abc000 and adding that number again ; abc000 + abc = abcabc
This works for 1001^n * a where a is a three digit number and a is less than 1001/n where n is an integer between 1 and 693.
the last Part is important. A less than 1001/n
Great videos man. Thats a channel I would love for my kids to watch
I have seen this before but this is still is interesting with it being 1001.
mfs who chose 000 as their 3 digits :
000,000
@@dak_attack1089pretty sure it would just be 0 by itself on any calculator, but I get your point 😂

I have just learned that 1,001 is not prime. Thank you sir.
indeed, it has three prime factors
And the middle was 690, which is not only nice tenfold, but also 345×2!
Which is 1000*1*2... Of course
One lab accident away from being a super villain 😂❤
345,690,345 is Cooler than just the 345 at the beginning and the end. 690 is also 345x2
Hey so i found something that’s pretty cool. I figured this out when i was around 10 or 11, im 13 now and have been waiting to tell someone.
So, grab any four digit number. Take the absolute value of the difference between the first and second digits, then take that as the first digit of the new number. Then repeat this for the 2nd and 3rd digit, 3rd and 4th digit, but then you do the difference between the last and 1st digit. The new number should be an entire different number, but repeat this process now again for the new number. Repeat this enough times for literally any number and it will always eventually come out to 0000. I honestly have no idea how this works but it does, and its pretty fun to mess around with on some notebook paper.
Cool! I've found it takes 8 iterations of this to make any positive 4 digit number go to 0
It works because you're telling everybody the answer is random. When you multiply two numbers your answer is never random
Finally, a short that impressed me and was worth watching. Kudos to you!!!
Also the middle number is the number doubled. 345x2=690
First one works because 7*11*13 = 1001. By how the decimal system works, it pretty much concetenates the number to itself times 1, which is the number itself at an interval of 3 since every 3rd spacing past the first 1 is also a one.
The second one is more interesting. This happens because the middle three numbers will always be number*2 since 1001^2 = = 1002001. 499 is fine here and evades any problems, but once you go 500 it will make 1000 and carry over a 1 into your first three digits.
Your videos kick a$$!
If the number is small enough:
If u do it twice, the number in the middle is double the original. If u do it 3 times, the 2 numbers In The middle are triple the original number.

Yes, because the average youtuber has the math education of a caveman, the attention span of a tik tokker, the dopamine system of a chainsmoker, and thinks numbers will dirty your clothes.
I should really get a life.
Oh, Indoor.
Do this repeatedly with 111. It is perhaps my favorite.
That's worthy of a like and share
Cool trick for a kid learning primes numbers to have some fun in school.
All I can hear is "Number 15: Burger King Foot Lettuce"
All I heard was "number fifteeeeeen burger king burgeeer, the last thing you want on your burger king burgeeer is somebody else's foooot funguuuus"
the number in the middle is twice the starting number
What is that device in your hand and where are the clocks!?
Remember this from school, you pick a 3 digit number, say 852 then type it in again, to get 852852.
Then divide by 7,11,13 and you get 852 again.
Not rocket science though.
Use 12345679 x with any numbers you want it will get so cool
Also, the middle 3 digts of the 9 digit answer is double the first and last 3!
The middle number 💀
Very good 💯👏
Nice one, thanks!
And the middle of the 9 digit number also has exactly double of your original number as the middle 3 digits (at least in this example, not sure where it breaks. 500 again?). Neat trick.
4th prime is 5
Also if you do it with a very small number with 3 digits (like 100) by doing this again and again you get a sequence that in my language is called tartaglia's triangle
100.100 (1 1)
100.200.100 (1 2 1)
100.300.300.100 (1 3 3 1)
100.400.600.400.100 (1 4 6 4 1)
This is a very cool trick!
Overall, you can randomly do anything with any numbers and come up with a weird creepy pattern, lol!
Yes, I figured it out. It's magic....
Why didn't you mention that the sum of the first and third numbers added together, equal the center number??
It’s a cheap magicians trick.
Idk why but he always looks like he knows where you live
Notice that the center after the second time he did it was twice the original number. This only works if the original number is less than 500.
Did you know that Pascal’s triangle numbers are powers of eleven? Cuz 1=11^0,11=11^1,121=11^2 and so on and on and on forever and ever
Do you have it with any 4 digit number.
This guy is Sheldon cooper long lost brother
The middle number was the two numbers on the side added together
Also noticed that the middle three digits is the double of the original number
Mmm. Love those primes.
5 is a prime number 🔥
There are loads of these little number curiosities, each of which is in itself very interesting. But what I find much more interesting and which I have not yet seen or heard even mentioned, anywhere, is any clue as to how these number-curiosities are discovered in the first place. - I mean, the possibilities are *infinite*-which suggests that there is at least one such number-curiosity associated with *every* number.
Is that it?
Reading comments: Some people get the 1001 concept some don't.
I didn't know Hans Niemann was good at math too. Since he's so good at math, perhaps he didn't cheat after all.
The 2nd one isn't random at all, I've seen it in programming, but it starts with a 3 I think
345 690 345 is strangely the middle is the sum of 345 + 345.
That's because he multiplied 345 twice
This guy is dream but for maths 💀
I picked 000 as my number and it worked!
This is great. 😂
Double round works also for 642
if I was smart enough to figure this out I wouldn't be watching this.
7x11x13=1001, and if you multiply a number by 1001 it would equal the three digit number twice side by side, Because if you multiply by 10, 100, 1000, Etc. the number would move to the left depending on if it's 10, 100, 1000, Ect
And if you do 345+345 you can see at the end that the result is the number in the middle
If he just didn't look like he escaped from an insane asylum
the first 3 primes are 1 2 and 3 👁️👄👁️
7*11*13 = 1001
Suppose your number was ABC, meaning the answer will be ABC000+ABC = ABCABC
try using 9091 and 101, and pick any 6 digit number instead
I do this in my head subconscious cuz i think its fun.
You're multiplying, so you're basically just adding it to itself so many times. Of course it's going to repeat eventually and even show up at the beginning and end a time or two.
I showed my wife and she loved it 😊
Also, the number in the middle is the double! Nice
I’m flabbergasted 😂😂😂😂😂
This guy looks like Luke Dunphy
That’s pretty normal given that you are multiplying by 1001
Whoa! What a cool party trick
Because 7*11*13=1001 which means any 3 digit number repeats itself just like multiplying one digit number by 11
I want add something
After second round the middle number is twice of our assumed one
If you just do 7x11x13 lots of times, then it shows rows of Pascal’s triangle
I had similar answers when I was doing something with exponents. I can't remember what I did now but I was getting the same type of numbers.
Wow if u add 345 + 345 it equaled the middle 3 numbers on the calculator 690
My guess is its got something to do with the 7 eleven store. Prove me wrong.
so how do we know we picked the exact number?
"Sir how are you paying for that sandwich?"
Do it withput calculator
Doesn't really have anything to do with the primes, just that they multiply to equal 1001
101 × any two digit (ab) will result in a number (abab)
1001 × any three digit (abc) will result in (abcabc)
1001× any four digit.... and so on
Try yourself 101 × three digit, four digit...
.... 1001× five digit.. and find out the cool stuff yourself
Do it with 826 twice and the left number is wrong
doing it again doubles the amount being in the middle of the longer number...
and 7×11×13013×1001=1003003001. Because
if you take ABC and do the trick thrice, if your number is less than 334, you get ABCDEFDEFABC. Where DEF is a 3 digit number that is ABC × 3. Otherwise the 1st 3 digits won't add up to your non-100-to-333-3-digit integer.
Everyone:explaining why it works
Me thinking about how he forgot the number 9:
It's like creating a illusion
Can you explain why this works?
7×11×13×1001=1002001.
That's why if you take 123,246,123 and divive it by 7, then 11, then 13, and then 1001, you get 123.
