## How to Find a Gamma Function Value?

The gamma function is an extension of the factorial function. The gamma function for any number n is given as:

**Γ( n) = (n - 1) !**

**Solved Example:**

What is the value of the gamma function for the number 7

**Solution:**

Gamma function Γ(`n`) = (n - 1) !

Here n = 7

So, Γ(*7*) = (7 - 1) !

Γ(7) = (6) !

Γ(7) = 720

The value of the gamma function for number 7 is 720

Similarly, you can try the calculator for the following:

- n = 5
- n = 12.4
