#include<algorithm>
#include<vector>
using namespace std;
int main()
{
int t;
cin>>t;
for(int j=0;j<t;++j)
{
long long r,S,p;
cin>>r>>S>>p;
vector<long long> seq(p);
seq[0]=1;
long long sum=1,ans=-1;
if((sum%p)==S)
{
ans=1;
}
else
{
for(long long i=2;i<p;++i)
{
seq[i-1]=(seq[i-2]*r)%p;
if(count(seq.begin(),seq.end(),seq[i-1])>1)
{
break;
}
sum+=seq[i-1];
if((sum%p)==S)
{
ans=i;
break;
}
}
}
cout<<ans<<endl;
}
return 0;
}```
