Jan 26, 2023 · In this article, you will learn how to find the gcd of two numbers in python using for loop, recursion, function, and Euclidean Algorithm. GCD = 10. What is GCD of Two Numbers? The GCD is the largest integer number of two positive integer numbers that can exactly divide both numbers without remaining a remainder.

Feb 22, 2025 · The task of finding the GCD (Greatest Common Divisor) of two numbers in Python involves determining the largest number that divides both input values without leaving a remainder. For example, if a = 60 and b = 48, the GCD is 12, as 12 is the largest number that divides both 60 and 48 evenly.

Jan 9, 2022 · I am trying to find the Greatest Common Divisor of 2 numbers using for loop, when I enter 2 numbers and one is divided by second without reminder it returns a correct answer, for example GCD(18,6)

Basically, the GCD (Greatest Common Divisor) or HCF (highest common factor ) of two numbers is the largest positive integer that divides each of the integers where the user entered number should not be zero. gcd = i. print("GCD of", num1, "and", num2, "is", gcd) while num1 != num2: if num1 > num2: . num1 -= num2. else: .

In this example, you will learn to find the GCD of two numbers using two different methods: function and loops and, Euclidean algorithm

Method 1: Using For Loop to find GCD of two numbers In the example below, for loop is used to iterate the variable i from 1 to the smaller number. If both numbers are divisible by i , then it modifies the GCD and finally gives the GCD of two numbers.

Jul 26, 2019 · Python GCD Program with for statement – This Programming tutorial will explain a simple logic and Python code to find GCD. A simple for loop statement is used to calculate Greatest common Divisor of the two given numbers.

Python provides multiple efficient ways to compute the Greatest Common Divisor (GCD) in Python of two numbers, which are of various levels of complexity and coding preferences. Using Python's Built-in math.gcd Function; Implementing the Euclidean Algorithm; Iterative Method; Recursive Approach; Using a For Loop

Mar 23, 2022 · We can use the built-in gcd() function, which is available in the math module to find gcd of 2 numbers. We can find gcd using one of the popular algorithms, i.e., Euclidean Algorithm to calculate the GCD.

Nov 3, 2022 · Python Program to Find HCF of Two Numbers using For loop. Follow the below steps and write python program to find HCF or gcd of two numbers using for loop:: Take input two number from the user; Iterate for loop to find HFC Or GCD and store HFC Or GCD value in variable; Print HFC Or GCD of given number
