If p and q are both odd prime numbers andp < q, then how many different positive integer factors does2pqhave?
Choose the correct choice from the following.
A) 3
B) 4
C) 6
D) 8
E) 12

Rationale: p and q are both odd prime numbers - it means either p or q is not 2 and since prime numbers have only two factors - 1 and the number itself p and q each will have ( 1 + 1 ) = 2 factors hence 2 pq will have ( 1 + 1 ) ( 1 + 1 ) ( 1 + 1 ) = 8 factors d is the answer
Answer: D
