Python | math.gcd() function

In Python, math module contains a number of mathematical operations, which can be performed with ease using the module. math.gcd() function compute the greatest common divisor of 2 numbers mentioned in its arguments.

Syntax: math.gcd(x, y)

Parameter:
x : Non-negative integer whose gcd has to be computed.
y : Non-negative integer whose gcd has to be computed.

Returns: An absolute/positive integer value after calculating the GCD of given parameters x and y.

Exceptions : When Both x and y are 0, function returns 0, If any number is a character, Type error is raised.
