Vasya likes to solve equations. Today he wants to solve $(x~\mathrm{div}~k) \cdot (x \bmod k) = n$, where $\mathrm{div}$ and $\mathrm{mod}$ stand for integer division and modulo operations (refer to the Notes below for exact definition). In this equation, $k$ and $n$ are positive integer parameters, and $x$ is a positive integer unknown. If there are several solutions, Vasya wants to find the smallest possible $x$. Can you help him?


-----Input-----

The first line contains two integers $n$ and $k$ ($1 \leq n \leq 10^6$, $2 \leq k \leq 1000$).


-----Output-----

Print a single integer $x$ — the smallest positive integer solution to $(x~\mathrm{div}~k) \cdot (x \bmod k) = n$. It is guaranteed that this equation has at least one positive integer solution.


-----Examples-----
Input
6 3

Output
11

Input
1 2

Output
3

Input
4 6

Output
10



-----Note-----

The result of integer division $a~\mathrm{div}~b$ is equal to the largest integer $c$ such that $b \cdot c \leq a$. $a$ modulo $b$ (shortened $a \bmod b$) is the only integer $c$ such that $0 \leq c < b$, and $a - c$ is divisible by $b$.

In the first sample, $11~\mathrm{div}~3 = 3$ and $11 \bmod 3 = 2$. Since $3 \cdot 2 = 6$, then $x = 11$ is a solution to $(x~\mathrm{div}~3) \cdot (x \bmod 3) = 6$. One can see that $19$ is the only other positive integer solution, hence $11$ is the smallest one.
