Hi all...

I'm using VB6 to write a program in which I need to factorize big numbers up to 10^20.
I already tried a few algorithms, but eather they can't generate big enough primefactors or they are much to slow...

Now I wonder if there doesn't exist an API-function (is that the right name?) that I can use. Something from the kernel32-lib or so...

Or, as last resort: is there an other (easy to learn) programming language that has better tools to do that kind of things?
