```cpp
#include <bits/stdc++.h>
using namespace std;
int main(){
long long a;
cin>>a;
if(a%3==0){
cout<<"3 ";}
if(a%5==0){
cout<<"5 ";}
if(a%7==0){
cout<<"7";}
if(a%3>0 && a%5>0 && a%7>0){
cout<<"n";}
}
```

这样的
```
#include<bits/stdc++.h>
using namespace std;
int main()
{
long long x;
cin>>x;
if(x%3==0)
{
cout<<"3 ";
}
if(x%5==0)
{
cout<<"5 ";
}
if(x%7==0)
{
cout<<"7 ";
}
else if(x%3!=0)
{
if(x%5!=0)
{
if(x%7!=0)
{
cout<<"n";
}
}
}
}
```
