Maths problem on Function

by amritanko » Thu Sep 10, 2009 11:19 pm
Hi

I have a maths problem, need a solution at the earliest as I have the exam tomorrow.

H(n) is the product of all even numbers from 2 to n.(n inclusive).
Find the smallest prime factor of H(100) +1.

Any help is welcome.

My Approach:

H(n) = 2n^2(1.2.3.... n/2)

After that I am getting stuck..

Please help.
