Learn about Factorial
A factorial is the product of all positive integers less than or equal to the number on which the operation is performed. Factorials are represented by placing an exclamation mark after the positive integer n of choice like so, n!. They are commonly used in number theory and counting problems to represent solutions. Our factorial calculator let's you pass a non negative number to it, and calculates the corresponding factorial. Use this tool to help you understand how factorials work!
Factorials are solved by expanding them, then multiplying all the expanded integers. For example, let's find the factorial of 5.Start by expanding 5 all the way down to 1. Now, multiply the assembled terms together to find the factorial of 5. The factorial of 5 is 120. Note that 0! = 1, and that factorials can only be positive numbers.
Starting from 6, multiply each number all the way down to 1.Starting from 10, multiply each number all the way down to 1.Starting from 15, multiply each number all the way down to 1.This is a factorial edge case, in which we already know that in the case that it is 0, we return 1.
