Just 60.
The only common multiple in that range is 100.
The least common multiple of the numbers 200, 100 and 180 is 1,800.
Just 77
Common multiples of 100 and 2 include any multiple of 100.
189, for one.
Short answer: There is not one. You could say that the greatest common multiple is infinity since there are an infinite number of common multiples. If you give a specific number as the greatest common multiple, you can always find a larger one by doubling it. For example, 9856 is a common multiple of 88 and 112. But, it is not the greatest common multiple. I can double it to make a larger common multiple: 19,712. I could multiply this one by 100 to make an even larger common multiple: 1,971,200. I can always make a larger common multiple.
100 is the first one.
There isn't one.
The least common multiple is one of the numbers when one of the numbers is a multiple of the other.
72 is the only common multiple of 24 and 36 that is less than 100, but more than 1.
One common multiple is 1500.
It is not possible to give a sensible answer to this question. The least common multiple (LCM) refers to a multiple that is COMMON to two or more numbers. You have only one number in the question!
