What is a Factorial?
In mathematics, the factorial of a non-negative integer \(n\), denoted by \(n!\), is the product of all positive integers less than or equal to \(n\).
For example, the factorial of 5 (denoted as 5!) is calculated as:
5! = 5 × 4 × 3 × 2 × 1 = 120
The factorial of 0 is defined as 1, i.e., 0! = 1. Factorials are commonly used in combinatorics, algebra, probability theory, and various other mathematical contexts. They represent the number of ways to arrange \(n\) distinct objects.
This tool helps you quickly calculate the factorial of any non-negative integer you input. Simply enter the number and click 'Calculate Factorial' to see the result.
