GMAT Prep2?? (J Divisible)

by dferm » Wed May 14, 2008 5:31 pm
Is the positive integer j divisible by a greater number of different prime numbers than the positive integer k?

(1) j is divisible by 30
(2) k = 1000

Can someone please help..

Thanks.

(1) j is divisible by 30
(2) k = 1000

(1)plug in 30 for j, 30 is divisible by 2, 3, & 5
(2) 1000 is divisible by 2 & 5

therefore (1) & (2) together the are sufficient, but insufficient alone
