Java中使用辗转相除法求最大公约数

public class T {
 public static void main(String[] args) {
 int gcd = gcd(91, 49);
 System.out.println(gcd);
 }

 /**
 * greatest commond divisor
 * @param a
 * @param b
 * @return
 */
 public static int gcd(int a, int b) {
 while(b != 0) {
  int temp = a%b;
  a = b;
  b = temp;
 }
 return a;
 }

}
