Gamma Function Calculator Γ


Enter a non-negative integer up to 50000, or a non-negative number up to 100 to calculate the gamma function of the value.

How to calculate the Gamma (Γ) function?

The gamma function can be computed using the equation:

$$( \Gamma \left( x \right) = \int\limits_0^\infty {s^{x - 1} e^{ - s} ds})$$

For positive integers, Γ(n) can be more simply calculated using:

$$( \Gamma \left( x \right) = (n - 1)!)$$

For example, Γ(5) = 4!
