Factorial Calculator: Fast, Simple, and Free Online Tool

What is a Factorial?

A factorial, represented by the symbol "!", is the product of all positive whole numbers up to a given number. For example, the factorial of 4 (written as 4!) is 4 x 3 x 2 x 1, which equals 24. Factorials are used in various areas of mathematics, including permutations, combinations, and probability.

What is a Factorial Calculator?

A Factorial Calculator is an online tool designed to compute the factorial of a given non-negative integer. The factorial of a number (denoted as n!) is the product of all positive integers less than or equal to that number.

It's a handy way to get accurate answers for math problems involving factorials without having to do the multiplication yourself.
