Factorial Calculator

The Factorial Calculator is a tool used to calculate the factorial of a given number, which is a common operation in mathematics and statistics.

What does the Factorial Calculator do?

The Factorial Calculator computes the factorial of a number, which is the product of all positive integers up to that number.

Factorial Calculator formula?

To calculate the factorial of a number using the “Factorial Calculator,” you can use the following formula:

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

This formula multiplies the number nnn by every positive integer less than it until reaching 1.

Factorial Calculator example?

Here are two examples of how to use the “Factorial Calculator”:

Example 1:

Let’s calculate the factorial of 5:

1. Start with the number 5.
2. Apply the formula:
   • 5! = 5 * 4 * 3 * 2 * 1
   • 5! = 120
     So, the factorial of 5 is 120.

Example 2:

Let’s calculate the factorial of 3:

1. Start with the number 3.
2. Apply the formula:
   • 3! = 3 * 2 * 1
   • 3! = 6
     So, the factorial of 3 is 6.

The Factorial Calculator simplifies the process of finding the factorial of any number, a fundamental operation in mathematics, useful for many applications in both theory and practice.
