**Instructions:** You can use this factorial calculator to compute the factorial of an integer number \(n\).

## More this factorial calculator

There are many Math contexts in which the use of factorials is relevant, especially in the field of Probability and Combinatorial, as the factorial of a number is related with the number of was \(n\) objects can be organized.

The formula for \(n!\) is:

\[n! = n \cdot (n-1) \cdot (n-2) \cdots 2 \cdot 1\]Notice that when \(n\) becomes large, the calculation of \(n!\) is more computationally involved. Typically, for large values of \(n\), you would use Stirling's Approximation, which provide a very accurate approximation.
