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<bits/stdc++.h>
using namespace std;

int main(){
  long long a, b;
  cin >> a >> b;
  
  // a =< b となるようにする
  if(a>b){
    long long c = b;
    b = a;
    a = c;
  }
    
  long long res;
  for(int i=1; i<a+1; i++){
    long long bi = b*i;
    if(bi % a == 0){
      res = bi;
      break;
    }
  }
  
  cout << res << endl;
  
  return 0;
