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<stdio.h>

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

int main()
{
	long long int a,b;
    scanf("%lld%lld",&a,&b);
  	long long int t=gcd(a,b);
  	long long int u=(a*b)/t;
  	printf("%lld\n",u);
  	return 0;
