可以参考我的代码：
```
#include<iostream>
#include<cstdio>
#include<cstring>
#include<algorithm>
using namespace std;
typedef long long ll;
const int a[]={0,2,3,5,7,11,13,17,19,23,29};
ll n,ans,mx;
void dfs(ll k,ll num,ll s){
if(num>n)return;
if(s>mx)mx=s,ans=num;
if(s==mx&&num<ans)ans=num;
if(k>10)return;
for(int i=0;num<=n;num*=a[k],i++)
dfs(k+1,num,s*(i+1));
}
int main(){
cin>>n;
dfs(1,1,1);
cout<<ans<<endl;
return 0;
}
```
