Learn how to find the GCD of two numbers in Python using 5 different methods including loops, recursion, math module, and more. Step-by-step examples inside.
# Define a function to calculate the greatest common divisor (GCD) of two numbers.defgcd(x,y):# Initialize gcd to 1.gcd=1# Check if y is a divisor of x (x is divisible by y).ifx%y==0:returny# Iterate from half of y down to 1.forkinrange(int(y/2),0,-1):# Check if bo...
We can find the GCD of any pair of numbers using a basic algorithm called theEuclidean algorithm. Euclidean algorithm is a method to find the largest number that can divide two other numbers without leaving a remainder. Think of two numbers, say21and49. Now, find the largest number that ca...
The highest common factor (H.C.F) or greatest common divisor (G.C.D) of two numbers is the largest positive integer that perfectly divides the two given numbers. For example, the H.C.F of 12 and 14 is 2. Source Code: Using Loops # Python program to find H.C.F of two numbers#...

For those who have trouble understanding summation notation, the meaning of G is given in the following code: G=0; for(i=1;i<N;i++) for(j=i+1;j<=N;j++) { G+=GCD(i,j); } /*Here GCD() is a function that finds the greatest common divisor of the two input numbers*/ ...
