```cpp
#include<iostream>
#include<cstdio>
using namespace std;
const int MAXN=100001;
int n,a[MAXN],b[MAXN];
void mod(int z;int x;);
int main()
{
cin>>n;
for(int i=0;i<n;i++)
{
cin>>a[i]>>b[i];
}
for(int i=0;i<n;i++)
{
mod(a[i],b[i]);
}
return 0;
}
void mod(int z;int x;)
{
int s_=0,max;
if(z>x) max=z;
else if(x>z)max=x;
for(int i=0;i<max;i++)
{
if(x%i==0&&z%i==0&&i>s_)
s_=i;
}
printf("%d\n",s_);
}
```

快读
```cpp
int read(char pos=' ')
{
short mul=1;
long long ans=0;
char c=getchar();
if (c=='-') mul=-1;
else ans=c-'0';
while (c!=pos&&c!='\n')
{
c=getchar();
if (!(c!=pos&&c!='\n')) break;
ans=ans*10+c-'0';
}
return ans*mul;
}
```
