[Java入门] 从键盘输入两个整数，求最小公倍数并输出

import java.util.Scanner;

public class GCD_LCM{
public static void main( String args[]){
Scanner s = new Scanner (System.in);
System.out.println("========计算两个数的最小公倍数========");
System.out.println("==============输入0 0结束=============");
int i=1;
while(true){
System.out.println("Case "+i+":\n请输入两个整数：");
int a = s.nextInt();
int b = s.nextInt();
if(a==0 && b==0) break;
int m = gcd(a,b);
int n = a*b/m;
System.out.println("最小公倍数为："+n+"\n");
i++;
}
System.out.println("===============输入结束===============");
}
public static int gcd(int a, int b){
if (b != 0) return gcd(b,a%b);
else return a;
}
}
