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.
The GCF of 72 and 180 is 36.
The lowest common multiple is 216
There is no such thing as a Greatest Common Multiple.
Least Common Multiple (LCM) for 72 180 is 360
It is the greatest multiple of 144
GCF (72, 144, 180) = 36
There is no greatest common multiple. Whatever value you may come up with, I can always add their lowest common multiple (72) to get a higher common multiple.
The greatest common multiple of any set of integers is infinite.
The greatest common multiple of any set of integers is infinite.
The greatest common multiple of any set of integers is infinite.
The greatest common multiple of any set of integers is infinite.
The Greatest Common Factor (GCF) is: 36
