The factorial is a mathematical operation that involves multiplying a given positive integer by every positive integer less than it down to 1. It is denoted by the symbol "!" after the number.

The factorial formula is: **n! = 1×2×3×4×...×n**

For example:

3! = 1×2×3 = 6

4! = 1×2×3×4 = 24

5! = 1×2×3×4×5 = 120
