Problem Statement

Takahashi is organizing a party.

At the party, each guest will receive one or more snack pieces.

Takahashi predicts that the number of guests at this party will be $A$ or $B$.

Find the minimum number of pieces that can be evenly distributed to the guests in both of the cases predicted.

We assume that a piece cannot be divided and distributed to multiple guests.

Constraints

• $1 \\leq A, B \\leq 10^5$
• $A \\neq B$
• All values in input are integers.

Input

Input is given from Standard Input in the following format:

$A$ $B$

Output

Print the minimum number of pieces that can be evenly distributed to the guests in both of the cases with $A$ guests and $B$ guests.
