Python GCD code using math.gcd() function – This Python programming tutorial explains the method of finding GCD of two numbers using math module’s gcd() function.

### What is Python gcd() functin of math module

The math.gcd(a,b) function return the greatest common divisor of the integers a and b. Therefore, gcd(a,b) function will calculate the largest positive integer that divides both a and b. Note that gcd(0, 0) returns 0.

### Python GCD code using math.gcd(a,b) Function

# Write a Python program to find # GCD of two numbers using gcd(a,b) # function of math module # Author: www.EasyCodeBook.com (c) import math num1= int(input('Enter the first number=')) num2= int(input('Enter the second number=')) result = math.gcd(num1,num2) print('GCD of',num1,'and',num2,'is:',result)

### The output of the program using gcd() function

Enter the first number=60 Enter the second number=80 GCD of 60 and 80 is: 20 Another sample run of the program: Enter the first number=21 Enter the second number=101 GCD of 21 and 101 is: 1
