computer programming factorial

Make programming propagating very large team.?

I want to know how can multiply very large programs (C #) involving numbers that have numbers> 6000. This is a problem I'm finding the factorial of a very large (up 200,000). (Time and material is not a problem), but I need each digit of the answer stored in a text file. I read somewhere that this can be done in the same way we do the multiplication in the paper with a pencil and values can be stored in strings and use whole numbers for each digit. But I'm having trouble booting. Suggestions?

I hope you will help: there are some links that might help: http://www.webguest.com/Science/Math/Number_Theory Rusin ~ http://en.wikipedia.org/wiki/Bignum http://www.math.niu.edu / / Http://michael.dipperstein.com/arithmetic/ known-math/94/bignum
