@[duan1zhuo](/user/1014720) 万一…… $b$ 和 $c$ 需要约分呢？

@[duan1zhuo](/user/1014720) 约分用 `__gcd`

你们参考一下，全绿无红
```cpp
#include<bits/stdc++.h>
using namespace std;
int main(){
int a,b,c,d,e,f;
cin>>a>>b>>c;
for(int i=100;i>=1;i--){
if(a%i==0&&b%i==0&&c%i==0){
d=a/i;
e=b/i;
f=c/i;
cout<<min(d,min(e,f))<<"/"<<max(d,max(e,f));
return 0;
}
}
cout<<min(a,min(b,c))<<"/"<<max(a,max(b,c));
return 0;
}
```
