```cpp
#include<iostream>
#include<cmath>
using namespace std;
int main(){
int a1,a2,b1,b2,c1,c2,n,ans;
cin>>n;
cin>>a1>>a2;
cin>>b1>>b2;
cin>>c1>>c2;
int a,b,c;
a=a2*ceil(double(n)/a1);
b=b2*ceil(double(n)/b1);
c=c2*ceil(double(n)/c1);
ans=min(a,min(b,c));
cout<<ans;
return 0;
}

你比较大小那出了问题，a>=b，但是你不能确定b小还是c小
