Program

Following is the example to calculate the GCD of the numbers of an array.

Live Demo

public class GCDOfArrayofNumbers{    public static int gcd(int a,int b){       int res = 0;       while (b > 0){          int temp = b;          b = a % b;          a = temp;          res = a;       }       return res;    }    public static void main(String arg[]){       int[] myArray = {3, 6, 8};       int result = gcd(myArray[0],myArray[1]);       for(int i = 2; i < myArray.length; i++){          result = gcd(result, myArray[i]);       }       System.out.println("Gcd of n numbers is: "+result);    } }

Output

GCD of n numbers is: 1
