John is a student who recently learned about factors in his math class.

His teacher gave him a number $K$ and asked him to find the smallest factor of $K$ that is present within the range of $M$ to $N($inclusive$).$

Help John solve this problem.

Given three numbers $K,M$ and $N,$ write a program that reads $K.M$ and $N$ and prints the smallest factor of $\text{'}K\text{'}$ that is present within the range of $\text{'}M\text{'}$ to $N\text{'}($inclusive$).$ If no factor is found within the given range, print $=-1$ :

Input

The first tre of input contains a single integer representing $K$ the gven number,

The second tine of input contains two space$-$separated integers representing the range $M$ and $N$

Output
