GCD of Two Numbers in Java with Source Code

|

GCD of Two Numbers in Java – The greatest common divisor (GCD) of two nonzero integers a and b is the largest positive integer d such that d is a divisor of both a and b; that is, there are numbers e and f such that a = de and b = df, with d being the largest. gcd is the abbreviation for the GCD of a and b. (a, b).

Example Program:

package gcdoftwonumbers;

import java.util.Scanner;


public class GCDofTwoNumbers {


    public static void main(String[] args) {
        long n1, n2;
        Scanner sc = new Scanner(System.in);
        System.out.println("enter  number 1");
        n1 = sc.nextLong();
        System.out.println("enter  number 2");
        n2 = sc.nextLong();
        if (n1 > 0 && n2 > 0) {
            long result = gcdCal(n1, n2);
            System.out.println("Gcd of two numbers = " + result);
        } else {
            System.out.println("Please enter numbers greater than zero");
        }
    }

    static long gcdCal(long a, long b) {
        while (b > 0) {
            long temp = b;
            b = a % b;
            a = temp;
        }
        return a;
    }

}

Output:

enter  number 1
3
enter  number 2
1
Gcd of two numbers = 1

What is the importance of GCD of 2 numbers?

The notion may easily be extended to groups of more than two numbers: the GCD of a group of numbers is the largest integer that divides them all.

The GCD is employed in a variety of number theory applications, including modular arithmetic and hence encryption techniques like RSA.

What is the use of GCD of n numbers in Java?

The smallest positive integer that is a multiple of both is the least common multiple (LCM), but the greatest common divisor (GCD) of any two numbers is the greatest positive number that divides both. As a result, the LCM and the GCD will be the product of the two figures.

Project Details and Technology

Project Name:GCD of Two Numbers in Java with Source Code
AbstractGCD of Two Numbers in Java – We utilize greatest common factors with fractions all the time, and because fractions are so ubiquitous in everyday life, GCF is quite beneficial! You can successfully simplify a fraction or ratio by determining the GCF of the denominator and numerator. E.g. We can make 3045 easier to understand by knowing that its HCF is 15.
Language/s Used:Java
