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 C# (judge verdict: Accepted)

using System;
using System.Linq;
public class Test {
	public static int gcd(int x, int y) {
		if(y == 0) return x;
		return gcd(y, x % y);
	}
	public static int lcm(int x, int y) {
		return x / gcd(x, y) * y;
	}
	public static void Main() {
		string buf;
		while(!string.IsNullOrEmpty(buf = Console.ReadLine())) {
			string[] sc = buf.Split();
			int a = int.Parse(sc[0]), b = int.Parse(sc[1]);
			Console.WriteLine(gcd(a, b) + " " + lcm(a, b));
		}
	}
