Oh Come On!

Its a Composite Number..

Here is a place where you can download an Executable for the Seive of Erastothenes for generating Prime Numbers www.fpx.de/fp/Software/Sieve.html which you can compile into a list to use to try to factor the number...

BTW...I Never said it would be Easy!

There are other challenges which are easier, but they are for less money...

Here is a free Factoring Tool from

A better factoring tool that can handle more than 2400 digits can be found at:home.netcom.com/~jrhowell/math/software.htm
