The factorial of a natural number n is the product of the positive integers less than or equal to n. The factorial calculator allows you to find this number.

Calculating the factorial of a number

The online factorial calculator has the factorial function which allows to calculate online factorial of an integer.

The exclamation point is generally used as a notation of the factorial, the calculator allows to use this notation.

For example, for calculating the factorial of 5 , use the following syntax factorial(`5`), after calculation , the result 120 is returned. The following syntax can also be used to calculate the factorial 5!

For small numbers, the calculator is able to give the details of the calculations of factorial.

Syntax :

factorial(n), where n is a integer.

It is possible to use the exclamation point to calculate the factorial, n!

Examples :

factorial(`5`), returns 120
