Python GCD code using math.gcd() Function

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

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
