In general, try to start threads with questions that have the standard GMAT format (5 answer choices.) Within a given thread/topic, you should feel free to post whatever questions you like.

We know that a prime, by definition, only has two factors: 1 and itself. So the maximum # of factors in common would be two. (As an example, say p = 3 and q = 9. The two factors in common are 1 and 3.)

If we assume that q is a positive integer, then the two numbers will have to have '1' in common. For example, if p = 2 and q = 9, the two numbers would only share one factor, '1.'

David, what if q is 0?

An excellent question. Technically, 0 has an infinite number of factors. So if p = 2 and q = 0, we know that '1' and '2' are both factors of two, and every positive integer would be a factor of 0, so they'd share two factors (1 and 2) in common, though this doesn't feel intuitive. Typically, when we're talking about common factors and multiples, the GMAT will invoke the restriction that we're dealing with positive numbers.

That positive restriction is a definite characteristic of the GMAT: "the maximum is infinity" does not sound like something that would appear on the GMAT in any form.
