Gamma function calculator is an online mathematical calculator which helps to find out the gamma function. It is nothing but the alternating representation of a factorial form. The mathematical representation is,

$\Gamma (n)$=(n-1)!

Step1: The gamma function equation is given by,
$\Gamma (n)$=(n-1)!
(n-1)!=1×2×3×....................×(n-1)
