 Allow us to signify by d(n) the amount of all divisors of the number n, for example d(n)=∑k|nk. 

 

For instance, d(1)=1, d(4)=1+2+4=7, d(6)=1+2+3+6=12. 

 

For a given number c, track down the base n to such an extent that d(n)=c. 

 

Input 

 

The principal line contains one integer t (1≤t≤104). Then, at that point, t experiments follow. 

 

Each experiment is characterized by one integer c (1≤c≤107). 

 

Output 

 

For each experiment, output: 

 

"- 1" in case there is no such n that d(n)=c; 

 

n, in any case.
