4! = 24

Explanation:

A factorial of a positive integer can be given by

n! = n × (n-1)! = n × (n-1) × (n-2) × ... × 1.

Which is the product of all positive integers less than or equal to n.

Or for any integer, the consecutive product of integers approaching 1.

4! = 4 × (4-1) × (4-2) × (4-3) = 4 × 3 × 2 × 1 = 12 × 2 × 1 = 24 × 1 = 24
