【cf 1108 B】multiset

1.题目链接。给你两个数的所有因子，把这个两个数找出来。十分easy，multiset秒之。

#include<bits/stdc++.h>
using namespace std;
int main()
{
	int n;
	cin >> n;
	multiset<int>s;
	for (int i = 0; i < n; i++)
	{
		int c;
		cin >> c;
		s.insert(c);
	}
	int v = *s.rbegin();
	for (int i = 1; i <= v; i++)
	{
		if (v%i == 0)
			s.erase(s.find(i));
	}
	int s1 = *s.rbegin();
	cout << v << " " << s1 << endl;
}
