How to Calculate Factorial?
The factorial of a number n means multiplying all integers from 1 to n.
Example: Factorial 5 (denoted as 5!) equals: 5! = 5 * 4 * 3 * 2 * 1 = 120.
So, the factorial of five means multiplying all numbers from 1 to 5, resulting in 120.
Note on Negative Numbers
We cannot calculate the factorial of negative numbers. Factorial calculation applies to positive numbers and zero. Zero is treated uniquely, so simply remember that 0! = 1.
Now you know how to calculate factorial. We hope the knowledge gained from this short article was useful.
