K = wxyz, where w, x, y, z are prime numbers. Not including 1 and K, how many factors does K have?	Pick
A) 7
B) 14
C) 21
D) 28
E) 35
Suppose w = 2, x = 3, y = 5 and z = 7. Then wxyz = 210.   To find out how many factors 210 has, go through different combinations of the prime factors as follows. You don't even need to calculate the answers but I have done so here:   (factor #1) 2   (factor #2) 3   (factor #3) 5   (factor #4) 7   (factor #5) 2 x 3 = 6   (factor #6) 2 x 5 = 10   (factor #7) 2 x 7 = 14   (factor #8) 2 x 3 x 5= 30   (factor #9) 2 x 3 x 7 = 42   (factor #10) 2 x 5 x 7 = 70   (factor #11) 3 x 5 = 15   (factor #12) 3 x 7 = 21   (factor #13) 3 x 5 x 7 = 105   (factor #14) 5 x 7 = 35   Since we are not including 1 and 210, answer = 14   ANSWER:14
