3 factorial, written as 3!, is the product of all positive integers from 1 to 3.
It is calculated as:
3! = 3 × 2 × 1 = 6
This concept is commonly used in permutations, combinations, and probability to determine the number of ways to arrange items. For example, 3 different books can be arranged on a shelf in 6 different ways.

January 17, 2026ELI5: What is a factorial and how does it work
To calculate the factorial of a number, multiply it by all whole numbers below it. For example, 5! = 5x4x3x2x1 = 120. One use of factorials is to find the number of permutations (orders). For example, if 5 people run in a race, any of the 5 people can finish first, any of the 4 remaining people can finish second, any of the remaining 3 people can finish third, any of the 2 remaining people can finish fourth, and the last remaining person finishes last. So there are 5! = 5x4x3x2x1 = 120 different possible race results. More on reddit.com
