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 PHP (judge verdict: WA: Presentation Error)

<?php
while(fscanf(STDIN, "%d %d", $a, $b)) {
	$gcd = $a > $b ? euclid($a, $b) : euclid($b, $a);
	echo $gcd, " ", $a * $b / $gcd, PHP_EOL;
}

function euclid($a, $b) {
	return $a % $b ? euclid($b, $a % $b) : $b;
}
?>
