        while(small!=0){                   //this method is called Successive divison method.  
            r=large%small;            //eg. : large=24, small =18, i.e.  r=6  
            large=small;                // large= 18 
            small=r;                       // small=6
            }
        System.out.println("GCD IS : "+large);
    }
    }
    OUTPUT: 
    ENTER TWO NUMBERS
    100
    50
    GCD IS : 50

Import java.io.*;
public class GCDExample { public static void main(String args[])
{ 
//Enter two number whose GCD needs to be calculated.
    Scanner scanner = new Scanner(System.in); 
System.out.println("Please enter first number to find GCD");
    int number1 = scanner.nextInt(); 
System.out.println("Please enter second number to find GCD");
    int number2 = scanner.nextInt();
System.out.println("GCD of two numbers " + number1 +" and " + number2 +" is :" + findGCD(number1,number2));
}
