There is no greatest common multiple of any set of numbers. Whatever number you say is their greatest common multiple, I can add their lowest common multiple and get an even greater number.
I suspect you want one of:
Greatest Common Factor (the highest (positive) number that divides into both without any remainder): GCF(72, 12) = 12
Lowest Common Multiple (the lowest (positive) number that is a multiple of both, that is they both divide into without any remainder); LCM(72, 12) = 72

BeauThere is really no such thing as a "greatest common multiple". Once you find the least common multiple of a set of numbers, you can keep adding the LCM to itself over and over again. Each new number you get will be a common multiple of your set of numbers, but each new number will always be larger than the previous. This means that you can keep adding while the number approaches infinity and you will still never find a greatest multiple.

What is the greatest common multiple of 72 and 180?
There is no greatest common multiple of two (or more) numbers: whatever number you come up with as the greatest common multiple I can always add their lowest common multiple to get an even higher common multiple. If you meant the LOWEST common multiple (the least number that both divide into with a remainder) then lcm(72, 180) = 360. If you meant the greatest common FACTOR (the greatest number that divides into both), then gcf(72, 180) = 36.
What are the greatest common factors for 60 and 72?
