### 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.

2 3

### Sample Output 1
