If x and y are both odd prime numbers and x < y, how many distinct positive R integer factors does 2xy have? Choose the correct answer:
A) 3
B) 4
C) 6
D) 8
E) 12
Since 2xy prime R factors are x^1*y^1*2^1, its total number or factors must be (1+1)(1+1)(1+1)=2^3=8. Thus, I think 8 would be the correct answer.
