Hi all,

I have found the following question on the GMAT prep software (EXAM2) :

"For every positive even integer n the function h(n) is defined as the product of all the positive even integers up to n included. Given the value h(100)+1 with p as its SMALLEST prime factor, p must be:

A. 240

Correct answer was E , but I can't find a reasonable explanation...anyone could help me with this?

It's clear that the number can be represented as 2^50 * 50! +1 , but from here I can't find a way to identify its prime factors.....

Many thanks

Teo
