In N is a positive integer less than 200, and 14N/60 is an integer, then N has how many different positive prime factors? Choose the correct choice from the following answers:	A) 2	B) 3	C) 5	D) 6	E) 8

Rationale: "14 n / 60 must be an integer . = > 7 n / 30 must be an integer . hence n must be a multiple of 2 * 3 * 5 . = > n has 3 different prime integers and can not have more than 3 different prime integers because 2 * 3 * 5 * 7 = 210 > 200 answer : b"
Answer: B
