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

#include <iostream>
using namespace std;

int gcd(int a, int b) {
  if(a % b == 0) {
    return b;
  } else {
    return gcd(b, a % b);
  }
}

int main() {
  long int a, b, c;
  cin >> a >> b;
  long int d = a, e = b;
  if(a < b) {
    c = gcd(b, a);
  } else {
    c = gcd(a, b);
  }
  cout << e * d / c;
}
