Find the Empirical Formula Given Percents

If you're given the Percent Composition of a compound, you can find the Empirical Formula for it. I have the shortest method ever to do it, although it's not a "full solution" like your teacher probably asks for.
1. Divide each % by the atomic mass of the element
2. Divide each of THOSE answers by whatever's smallest
3. Adjust these numbers into their lowest whole-number ratio.
