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 Scala (2.11.7) (judge verdict: Wrong Answer)

object Main extends App {
    val sc = new java.util.Scanner(System.in)

    val a,b = sc.nextInt

    println(lcm(a,b))
    
    def gcd(x:Int,y:Int):Int = if (y > 0) gcd(y,x%y) else x
    def lcm(x:Int,y:Int):Int = x/gcd(x,y) * y
}
