输入两个正整数m和n，求其最大公约数和最小公倍数

import java.util.Scanner;public class Main {    public static void main(String[] args) {        Scanner in = new Scanner(System.in);        int n = in.nextInt();        int m = in.nextInt();        System.out.println(gcd(m, n) + " " + m * n / gcd(m, n));    }    static int gcd(int a, int b) {        while(b != 0) {            int t = b;            b = a % b;            a = t;        }        return a;    }}
