I need some help on this one. Obviously, calculating out the product of all the even numbers between 2 and 100 is not the answer here. What's the shortcut? Thanks.
For every positive integer n, the function h(n) is defined to be the product of all the even integers from 2 to n, inclusive. If p is the smallest prime factor of h(100)+ 1, then p is
A. between 2 and 10
B. between 10 and 20
C. between 20 and 30
D. between 30 and 40
E. greater than 40
Answer is E.
