120

To find the factorial of a number, you multiply that number by all of the positive integers less than it down to 1. For 5!, this means you calculate it as follows:

5! = 5 × 4 × 3 × 2 × 1.

First, calculate the multiplication step-by-step:

1. 5 × 4 = 20

2. 20 × 3 = 60

3. 60 × 2 = 120

4. 120 × 1 = 120

So, the complete calculation for 5! results in 120.

This means the factorial of 5, denoted as 5!, is correctly determined to be 120. This value is essential in various areas of mathematics, especially in combinatorics, where it helps in calculating permutations and combinations.
