Thefactor countof an integer n greater than 1 is the number of distinct prime factors of n. For example, the factor count of 36 is 2, since 2 and 3 are the distinct prime factors of 36 = 2 x 2 x 3 x 3. For which of the following integers is the factor count greatest R?	Choose the correct choice.
A) 60 B) 61 C) 62 D) 63 E) 64
60 = 2*2*3*5 factor count =3   61= prime number   62 = 2*31 factor count=2   63=3*3*7 factor count=2   64=2*2*2*2*2*2 factor count=1=R   answer is 60.
