Sum of product of first N natural numbers.

Is there any existing formula or method to calculate the product of of first n natural numbers for extremely large values i.e n! ? I could not find anything on the internet.

Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

If you want a formula to calculate n! then you're stuck with the recursive definition: n! = n * (n-1)! with 0! = 1. You could also use the gamma function with n! = gamma(n +1), but you still have to do all the work.
