Python Program to Find the GCD of Two Numbers

Python program to find gcd of two numbers; In this tutorial, i am going to show you how to find GCD of two number or array elements.

GCD of two or more non-zero number is the largest number that divides both or more non-zero numbers. It is one of the basic concepts of mathematics.

Python program to find the gcd of two numbers

Now, i will write simple python program to find gcd of two numbers; as shown below:

  • Python program to find the GCD of two non-zero numbers
  • Python program to find the GCD of the array Elements

Python program to find the GCD of two non-zero numbers

  • Get input numbers from user in program
  • Include math module.
  • Find gcd by using math.gcd() function and store result in variable.
  • Print result.
#Python | Program to Find the GCD of the Array
# import math module
import math
# input two numbers
m,n=map(int,input('Enter two non-zero numbers: ').split())
#to find GCD
g=math.gcd(m,n) 
# printing the result
print('GCD of {} and {} is {}.'.format(m,n,g))

Output

Enter two non-zero numbers:  5 10
GCD of 5 and 10 is 5.

In the above python gcd program, you have learned to find the GCD of two non-zero number.

Python program to find the GCD of the array Elements

#Python | Program to Find the GCD of the Array
# importing the module
import math
# array of integers
A=[100,150,250,150,170,110,195]
#initialize variable b as first element of A
b=A[0]  
for j in range(1,len(A)):
    s=math.gcd(b,A[j])
    b=s
print('GCD of array elements is  {}.'.format(b))

Output

GCD of array elements is 5.
