factorials get BIG really fast and exceed the limits of 32-bit unsigned integer variables by 13!.
If you want to play with them use a datatype that can handle huge numbers, or switch to an extended precision mathematics library like GMP.

Or use Ruby or Python that do not have these narrow limits.

The only difference being that the arbitrary precision types are built into the language instead of offered as a library. I always enjoy when someone goes into a random thread and suggests that people use their favorite languages for no good reason.
