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 C (GCC 5.4.1) (judge verdict: Accepted)

#include <stdio.h> 
int main() {
  long A, B, r, x, tmp;
  scanf("%ld", &A);
  scanf("%ld", &B);
  x = A * B;
  if(A < B){
    tmp = A;
    A = B;
    B = tmp;
  }
  r = A % B;
  while(r != 0){
    A = B;
    B = r;
    r = A % B;
  }
  printf("%ld\n", x/B);
  return 0;
}
