I'm currently working in the Official Guide for GMAT Quantitative Review 2015 book and question 3 (page 153) in the DS section is;

If n is an integer, then n is divisible by how many positive integers?

(1) n is the product of two different prime numbers.
(2) n and $$2^3$$ are each divisible by the same number of positive integers.

This question is discussed here: https://gmatclub.com/forum/if-n-is-an-i ... 64964.html In case of any doubts please post there.

As for you questions: only positive integers can be primes. This is generally true, not only for the GMAT. GMAT doe snot have its won math.
