int gcd(int c,int d) {
   int temp;

      temp = d;
      d = c % d;
      c = temp;
   }
   return c;
}
int main() {
   int c[] = {8, 20, 32, 28};
   int n = 8;
   int r = c[0];
   for(int i=1; i<n; i++) {
      r = gcd(r, c[i]);
   }
   cout <<"The GCD of the four numbers is "<< r << endl;
   return 0;
