10的12次方咋干？long long又不够

#include<bits/stdc++.h>
using namespace std;
int main(){
	long long n;
	cin>>n;
	for (long long i=2;i<=s;i++){
		for (long long j=2;j<=s;j++){
			if (i*j==s){
				cout<<i<<" "<<"*"<<" "<<j;
				return 0;
			}else if (i*i*j==s){
				cout<<i<<"^"<<i<<" "<<"*"<<" "<<j;
				return 0;
			}
		}
	}
    cout<<n;
}
