# Gamma Function Calculator

Gamma Function is represented by Γ, the capital letter gamma from the Greek alphabet is a commonly used extension of the factorial function to complex numbers. Gamma function is only defined for all positive integers.

## What is a Gamma Function Calculator?

A 'Gamma Function Calculator' is a free online tool that calculates the value of the gamma function of the given number. In this calculator, you can enter the number and the gamma function will be calculated within a few seconds.

NOTE: Enter the values between 1 to 20 only.

## How to Use Gamma Function Calculator?

Follow the steps given below to use the calculator:

**Step 1:**Enter the number in the space provided.**Step 2:**Click on**"Calculate"**.**Step 3:**Click on**"Reset"**to clear the field and enter new values.

## 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
