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;

long long gcd(long long m, long long n){
   while (n != 0){
      long long t = n;
      n = m % n;
      m = t;
   }
   return m;
}
int main(){
   long long A, B;
   cin >> A >> B;
   long long Ans;
   Ans = A*B/gcd(A, B);
   //cout << gcd(A, B) << endl;
   cout << Ans << endl;
