Finding that integral is pretty difficult. You need to find an approximation with Taylor series, and the answer is not particularly nice...

Hi;

The gamma function is defined as

If it could be integrated then that would be the definition of the gamma function, not the integral.

In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
