求最小公倍數

輸入兩數，求出兩數間的最小公倍數

import java.util.Scanner;
 
public class Demo {
 
    public static void main(String[] args) {
 
        Scanner sc = new Scanner(System.in);
        int a = sc.nextInt();
        int b = sc.nextInt();
 
        int max = 1;
        for (int i = 2; i <= a; i++) {
            if (a % i == 0 && b % i == 0) {
                max = i;
            }
        }
 
        System.out.println(max);
        System.out.println(a * b / max);
 
    }
}
