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.

Sample Input 1

2 3

Sample Output 1

6

When we have six snack pieces, each guest can take three pieces if we have two guests, and each guest can take two if we have three guests.

Sample Input 2

123 456

Sample Output 2

18696

Sample Input 3

100000 99999

Sample Output 3

9999900000

Solution in Pascal (FPC 2.6.2) (judge verdict: Wrong Answer)

var a,b:longint;
tmp:int64;
begin
        readln(a, b);
        if b>a then begin
                tmp:=a;
                a:=b;
                b:=tmp;
        end;
        tmp:=a;
        while true do begin
                tmp:=tmp+a;
                if tmp mod b = 0 then begin
                        writeln(tmp);
                        break;
                end;
        end;
end.
