WAJP to find out the HCF of teo number

import java.util.Scanner;
class GCDOfTwoNumbers {
public static void main(String args[]){
int a, b, i, hcf = 0;
Scanner sc = new Scanner(System.in);
System.out.println("Enter first number :: ");
a = sc.nextInt();
System.out.println("Enter second number :: ");
b = sc.nextInt();

  for(i = 1; i <= a || i <= b; i++) {
     if( a%i == 0 && b%i == 0 )
     hcf = i;
  }
  System.out.println("HCF of given two numbers is ::"+hcf);

}
