What is the least positive integer that is not a factor of 30! and is not a prime number?  Pick one.
A) 31	B) 32	C) 33	D) 62	E) 64

Rationale: a ) 31 is prime and per the question stem we can not use this b ) 32 = 2 * 16 - within 30 ! we have a 2 and 16 so 32 will be a factor of 30 ! c ) 33 = 3 * 11 - again within 30 ! we have a 3 and an 11 so 33 will be a factor of 30 ! d ) 62 = 31 * 2 - bingo 31 is not included in 30 ! e ) 64 = 16 * 4 - both 16 and 4 are multiplied in 30 ! answer is d !
Answer: D
