GCM is greatest common multiple. GCM of 7 and 2 is 14, GCM of 8 and 2 is 8.

I thought that was the least common multiple. 'cause 16 is a multiple of 8 and 2 but is greater than 8.

Ha, you're right. I mixed up GCD and LCM. What the heck is the GCM?

There are a lot of factors to consider; what counts as passing, whether they tended to teach to the test, and what in the world the GCM of two numbers mean. But in general, I do think most tests here are too easy. I find it far more interesting when a test includes easy questions that progressively advance to impossibly difficult questions, but the tendency here is to boost self-esteem and make tests that feasibly most people can get 100% on at that age.
