可恶再度把添胜第3周没做完的愤怒发泄在题解上（？

最小公倍数指一个数能同时除以两个或以上的数，并且这个数是最小的，那这个数就是这些数 的最小公倍数。（不懂的话看五年级下册数学书去吧

这一题，能同时整除3和5的数也一定能整除3和5的最小公倍数15（15既能整除3又能整除5，而且15以内的正整数都不能同时整除3和5

上代码：

#include<bits/stdc++.h>
using namespace std;

int main(){
	int n;
	cin>>n;
	if(n%15==0)cout<<"YES";
	else cout<<"NO";
	return 0;
}

因为懒所以不加注释了，，
