Problem:
GCD and LCM

Write a program which computes the greatest common divisor (GCD) and the least common multiple (LCM) of given a and b.

Input

Input consists of several data sets. Each data set contains a and b separated by a single space in a line. The input terminates with EOF.

Constraints

0 < a, b ≤ 2,000,000,000

LCM(a, b) ≤ 2,000,000,000

The number of data sets ≤ 50

Output

For each data set, print GCD and LCM separated by a single space in a line.

Sample Input

8 6
50000000 30000000

Output for the Sample Input

2 24
10000000 150000000

Solution in Python3 (judge verdict: WA: Presentation Error)

import sys

def gcd(m, n):
    if n != 0:
        return gcd(n, m % n)
    else:
        return m

for line in sys.stdin.readlines():
    m, n = map(int, line.split())
    g = gcd(m, n)
    l = m * n // g    # LCM
    print(g, ' ', l)
