The Greatest Common Factor of 324, 180, 120 is 12.
The greatest common factor of the numbers 120 and 180 is 60.
The greatest common factor of the numbers 1,830 and 60 is 30.
60
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.
60, 120, 180 and so on.
The greatest common multiple of any set of integers is infinite.
The GCF is 15.
The LCM is: 1,800
The least common multiple of 180 and 156 is 2340. The greatest common factor is 12.
If you mean 90, 120 and 180 then the GCF is 30
