Web3 Answers. A good approximation for n! is that of Stirling: n! is approximately n n e − n 2 π n. So if n! = r, where r stands for "really large number," then, taking logs, you get ( n + 1 2) log n − n + 1 2 log ( 2 π) is approximately log r. Now you can use Newton's method to solve ( n + 1 2) log n − n + 1 2 log ( 2 π) = log r for n.
