For every positive integer n, h(n) is the product of all the even integers from 2 to n (inclusive). P is the smallest prime factor of h(100)+1. What is P=?
Since we have only even numbers multiplied and then we add a 1, we should get odd number. Shouldn't the smallest prime factor be between 2 nd 10? The answers are:
a) between 2 and 10
b)between 10 and 20
c)between 20 and 30
d)between 30 and 40
e)over 40
I was thinking that if it is the SMALLEST PRIME FACTOR it will be a 2 or 3 or 5 or 7....
