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 Kotlin (1.0.0) (judge verdict: Accepted)

fun main(s: Array<String>) {
  val (a, b) = readLine()!!.split(' ').map { it.toLong() }
  println(a * b / gcd(a, b))
}
 
fun gcd(a: Long, b: Long): Long {
    if(a < b) return gcd(b, a)
    if(b == 0L) return a
    return gcd(b, a % b)
}
