Amazing videos
how to find for 18,30,24?
Good, though the only negative is you will have to somehow learn your time-tables quickly and mentally be able to calculate them immediately ( I mastered it a long time ago) but other than that I think its a pretty good solution.
Masha Allah
Genius sir you would be the principal of Loyola school
I never saw this type of teaching ,

How to find LCM when the highest number does not divides the two numbers from the given. Please guide sir
Thank you so much sir for your guidance it really helps to find LCM 👌👌
+Ashu rocks ....Do share the videos
Suresh Aggarwal + sure😄
Wow sir thanks
Just after watching your video I just figured out this ability of mine in me that just by observing the number I can tell its LCM
Thank u... Sir.. Great and fine presentation 😍
One thing i want to mention that...
While finding LCM...
WHEN we go for next multiple of highest no.... When two other no.. Are not multiple of highest no... Then after finding 1st number's multiple, when you meed to find next numbers multiple, u need to take multiple of,which no. You selected for 1st number.. And not of original highest no.
E. G.. Lcm of 40,50,60...??
Take 10 as default and multiply it by the LCM of 4, 5 and 6
Tnxq a lot sir ,lots of respect and love from us......🤗🤗

Sir this is VASTAV MAHANT of class 8.My board is ICSE.Ur explanation is great and simple.Pls keep going on making vedios.
Today I Know the very short trick... thanks sir
This is good to combine (in a way) with the ladder method. Meaning that if that if the rule applies, as in your first example, you can just avoid doing any other steps.
Very helpful tips💡.
Thank you so much Sir
Thank you sir ... For spending your valuable time and it was a great class ... Waiting for your next classes ... great 🙏
Its fun learning in this way
Thank u sir, for helping me. Hope you can give us more videos : )
I knew that .... I had been using this since fourth standard ....... but I did not know it was a trick .....I thought it was a common logic that everyone knew about and used

You are the very nice teacher of maths really,☺☺
Thanks for your efforts sir, I know why Fans are off in your room and you are just sweating there, So that video won't catch extra noise . 🙏😀
Thanks for understanding....do share the links with your WhatsApp groups and contacts
Awesome Trick Sir...Thank you
Thank you very much, Sir!! Sir, when I applied the same method for calculating the LCM of 2,4,6,8,10 and 12, I got the answer as 60. But, the correct answer is 120. 12 is a multiple of 2,4, and 6, but not of 8 and 10. So, 12*2=24, 8 divides 24 by 3. But, 24 is not a multiple of 10. Therefore, 12*5=60, 10 divides 60 by 6. Hence, according to the methods taught in the video, 60 has to be the LCM. Could you please mention the correct solution for this sum, Sir?
Pl sir explaine this
Sir super ur teaching method is nive plz keep more bideos about different types of sums
I am fan of your trick s subscribed
Thanks you saved me from my tutor
Why are Asian math teachers so smart?
Thanks for ur videos. Today students are very luck.

Thanks. Do share the links with your WhatsApp groups and contacts
I love your way of teaching and technic
What if the highest number is a prime number???
Please reply fast.
Give numbers
life saver thanks a lot may god bess you
It would be really helpful if you leave some questions in the end for us to solve and then you can explain how to do that, so we can see whether we really understand the method
nicely taught sir thank u
Sir please tell me the LCM of 63,70,77 by this trick with explanation.
Ok so we can clearly see that they are all a multiple of 7.
So what we would do is :
7( 9:10 : 11)
We put 7 in the LCM and we also know that 11 is a prime number
So we would multiply it all to get the product.
7x9x10x11= 6930
The answer is 6930
sir suppose we have odd no. instead of place prime no, so we follow same procedure?
Very nice teacher
Excellent trick..very helpful
Thanks a lot sir sir please teach more types of examples of different sums like...

You are the greatest teacher ever..❤️ ❤️ ❤️
If all the digits are not multiple what will we do at that time.
+Manjesh kumar....for coprime numbers the LCM is their product
If there are three co prime numbers,then what is the hcf of those numbers
Thank you so much sir
Some times it will very complicate to find
very very helpful videos thanks sir
Sir you are amazing and no.1 teacher who teaches shortcuts
I have never seen teacher like you
You are amazing sir👌👌👌
Sir all numbers are multiple of 50 is a wrong statement. Correct statement is ALL THE NUMBERS ARE FACTORS OF 50. You said that when prime number left with the highest number then no need of taking LCM just multiply the both numbers. But I think when the highest number is the multiple of prime there is no need to multiplication. Regards Surendra Singh , Maths teacher
+The Maths Guru.....agree to first part (was just an error) but not to second part
it os a gud mthod....but...dis trick doent work wid this given question......lcm of 24,36,44,62..?? please find d solution...nd reply me as soon as possible
hello " anjali mishraa" do u find the answer which was u mention in the comment?? really it contain some kind of difficult while doing big numbers... if u find any trick plz inform me dude
according to sir's method,
step 1:search for prime numbers in the given numbers
there is 11 in 44 , and 31 in 62 . so 11*31 will be the part of LCM anyway!
step 2: look for the biggest number apart from 11,31
we have 24,36,2,4
cancel 2,4 as they divide the biggest number,36
check: is 24 divides 36? no!
now,36*2=72, and24 divides 72 perfectly.
therefore, LCM=72*11*31
hope it helps!
@@shaikgouse770 my way of finding lcm to this question is
2^3*3^2*11*31=8*9*11*31
(8 in 24,9 in 36,11 in 44, 31 in 62)
method: multiplication of the highest powers of all prime factors!
@@mounikabhupathi2012 tqq u dude
For large numbers 1.write them in standard form.
2. Write down all prime numbers .
3. Raise their highest power.
4. Multiply them.. resultant product will be the LCM.
You are great sir... Thank you...
excellent...
Thank you
This method is easy and simple and quick and the best
