Python math.gcd()

Contents

math.gcd(*integers) function returns the Greatest Common Divisor (GCD) of the integers passed as arguments.

The syntax to call gcd() function is

math.gcd(*integers)

where

Parameter	Required	Description
*integers	No	None, one or multiple integer values.

If no integer value is passed as argument to gcd(), then the return value is 0.

If only one integer is passed to gcd(), then then same value is returned as GCD.

If any non-integral value is passed as argument to gcd(), then the function raises TypeError.

GCD of two integers: 10 and 25.

Python Program

import math

result = math.gcd(10, 25)
print('gcd() :', result)

Output

gcd() : 5

GCD of one integer value.

Python Program

import math

result = math.gcd(25)
print('gcd() :', result)

Output

gcd() : 25

GCD of arguments containing floating point values.

Python Program

import math

result = math.gcd(25.5, 2.6)
print('gcd() :', result)

Output

TypeError: 'float' object cannot be interpreted as an integer
