题解 | 求最小公倍数

import java.util.*;

public class Main {
    public static void main(String[] args) {
        Scanner console = new Scanner(System.in);
        int m = console.nextInt();
        int n = console.nextInt();
        int result = getCM(m, n);
        System.out.println(result);
    }

    public static int getCM(int m, int n){
        int max  = Math.max(m,n);
        int min  = Math.min(m,n);
        while(min!=0){
            int temp = max%min;
            max  = min;
            min = temp;
        }
        
        return m*n/max;
    }
}

求出来最大公约数。用两数相乘除去最大公约数。
