If X represents the product of the first 15 positive integers, then X is not a
multiple of:  Pick one
A) a) 99  B) b) 84  C) c) 72  D) d) 57  E) e) 67
a) 99 = 9*11   b) 84 = 4*7*3   c) 72 =9*11   d) 65 = 5*13   e) 57 =19*3   since 19 is not there in first 15 positive numbers it is the only possibility   d) 57)
