What is the value of 4 factorial (4!)?

The value of 4 factorial, denoted as 4!, is calculated by multiplying all whole numbers from 4 down to 1. This means:

4! = 4 × 3 × 2 × 1

Calculating this step by step:

• First, multiply 4 by 3, which equals 12.

• Next, multiply that result (12) by 2, giving you 24.

• Finally, multiply 24 by 1, which remains 24.

Thus, 4! equals 24, confirming that the correct answer is indeed 24. This concept of factorial is crucial in various fields of mathematics, including combinatorics, where it is used for finding the number of ways to arrange or choose items.
