Apr 4, 2025 · GCD (Greatest Common Divisor) of two given numbers A and B is the highest number that can divide both A and B completely, i.e., leaving the remainder 0 in each case. GCD is also called HCF (Highest Common Factor). There are various approaches to finding the GCD of two given numbers. Approaches:

The HCF or GCD of two integers is the largest integer that can exactly divide both numbers (without a remainder). Example 1: Find GCD of two numbers using for loop and if statement

The greatest common divisor (GCD) of two integers a and b is the largest integer that is a factor of both a and b. The GCD of any number and 1 is 1, and the GCD of any number and 0 is that number. One efficient way to compute the GCD of two numbers is to use Euclid's algorithm, which states the following:

Mar 28, 2021 · GCD (i.e. Greatest Common Divisor) or HCF (i.e. Highest Common Factor) is the largest number that can divide both the given numbers. Example: HCF of 10 and 20 is 10, and HCF of 9 and 21 is 3.

Feb 14, 2025 · In this tutorial, we’ll look at three approaches to find the Greatest Common Divisor (GCD) of two integers. Further, we’ll look at their implementation in Java. 2. Brute Force. For our first approach, we iterate from 1 to the smallest number given and check whether the given integers are divisible by the index.

Here is my complete code example of how to find the GCD of two numbers in Java. This Java program uses Euclid's method to find the GCD of two numbers. They must be an integer, so make sure you check the numbers entered by the user like floating-point numbers are not allowed.

Methods in Java Java Code Example: Greatest Common Divisor (GCD) The Greatest Common Divisor (GCD) of two numbers is the largest number that divides both numbers without leaving a remainder. For example, the GCD of 48 and 18 is 6 because …

In this article, we will cover different methods to find the GCD of two numbers in Java, including loops, recursion, the Euclidean algorithm, and Java's built-in gcd () method, with practical examples and analysis. The Greatest Common Divisor (GCD) of two numbers is a crucial concept in mathematics and computer science.

public class GCD { public static void main (String [] args) { int n1 = 81, n2 = 153, gcd = 1; for (int i = 1; i <= n1...

In this tutorial, we will write a Java program to find out the GCD of two numbers. The GCD (Greatest Common Divisor) of two numbers is the largest positive integer number that divides both the numbers without leaving any remainder.
