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 Python (3.4.3) (judge verdict: Runtime Error)

a = input("")
b = input("")

A = int(a)
B = int(b)

if (A < B):
    tmb = A
    A = B
    B = tmb

while (A > 0)and (B >0):
    A = A - B
    if (A < B):
        abc = A
        A = B
        B = abc
c = str(A)
d = str(B)
if (A > B):
    GCM=int(c)
elif (A < B):
    GCM=int(d)
P=int(a)*int(b)
lcm=P//GCM
print(str(lcm))
