What is my mistake in this code?

#1

public class hcd {

public static void main(String[] args) {
	
	int dividend = 60;
	int divisor = 36;
	
    int rem = dividend/divisor;
	
	while(rem!=0) {
		int res = rem;
		dividend = divisor;
		divisor = res;
	}
	
	System.out.println(divisor);
	
	

}

}

#2

Inside the while loop, you need to calculate the remainder again.
