What is the first 8 digits of 50!?

Please show how you got it. I only heard the problem before but I do not know how to solve it. By the way, n! means multiplying all the numbers from 1 to n.

50! means 50 factorial.

Most calculators can do this in 2 or 3 button presses.

The answer is 3.04140932 x 10^64
