There can be no GCM (Greatest Common Multiple). Suppose a GCM exists and suppose it is x. That is, x is the GCM of 7 and 13, then 2x is a multiple of both 7 and 13 and is greater than x. This contradicts the statement that x is the GCM. So x cannot be the GCM.

The greatest common multiple of any set of integers is infinite.

The GCF is 5. The LCM is 225. The GCM is infinite.

6=2*3 7=7 8=2*2*2 6 and 8 both have 2's, but 8 has more. Cross out the 2 from 6. 3*7*2*2*2 =168

The GCF is 5. The LCM is 225. The GCM is infinite.

If GCM stands for Greatest Common Multiple, there is no such number. This is because if x is claimed as the GCM then 2x is a common multiple of both 6 and 8 and 2x > x.
