If m and n are both odd prime numbers andm < n, then how many different positive integer factors does2mnhave?  Choose the correct choice from the following options:
A) 3	B) 8	C) 6	D) 4	E) 12
m and n are both odd prime numbers- It means either m or n is not 2   and since prime numbers have only two factors - 1 and the number itself   m and n each will have (1+1)=

2 factors   Hence 2mn will have (1+1)(1+1)(1+1)= 8 factors   8 is the answer
