利用辗转相除法求最小公倍数

import java.util.Scanner;

public class Main {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		Scanner in=new Scanner(System.in);
		int a=in.nextInt();
		int b=in.nextInt();
		System.out.println(a/gcd(a,b)*b);
	}

	private static int gcd(int a, int b) {
		return b==0?a:gcd(b,a%b);
	}
