Best Answer

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.

There can be no GCM since given any number with a claim to being a GCM, twice that number will be greater and it will be a common multiple.
