# What is the Factorial of 100?

For few days “factorial of 100” is one of the trending topics and many of the maths geeks calculate using their voice assistant devices like Alexa, Shiri, etc. In this new post of MathDart, I’ll show you how to compute the factorial of 100 with a really fast, step-by-step explanation of how the 100 ! is calculated. For one thing, what precisely is a factorial? The factorial is the aftereffect of increasing all entire numbers in a picked number (for this situation 100) right down to 1.

You will generally see factorials expressed with an exclamation mark (!) after the number, like so: 100!

The factorial of a non-negative integer n, denoted by n!, is the product of all positive integers less than or equal to n: n!= n * (n-1) * (n-2) * … * 2 * 1

## What is the Factorial of 100?

So let’s take 100! and calculate the factorial by multiplying each whole numbers:

100 x 99 x 98 x 97 x 96 x 95 x 94 … = 9.3326215443944E+157
