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: Wrong Answer)

using System;

namespace _0005 {

	public static class Program {

		public static void Main() {
			string input;
			while (!string.IsNullOrEmpty(input = Console.ReadLine())) {
				var splitStr = input.Split(' ');
				var a = int.Parse(splitStr[0]);
				var b = int.Parse(splitStr[1]);

				Console.WriteLine("{0} {1}", GCD(a, b), LCM(a, b));
			}
		}

		private static int LCM(int m, int n) {
			return m * n / GCD(m, n);
		}

		private static int GCD(int m, int n) {
			int a = Math.Max(m, n);
			int b = Math.Min(m, n);
			int r;

			while ((r = a % b) != 0) {
				a = b;
				b = r;
			}
			return b;
			//if (m < n) {
			//	return GCD(n, m);
			//}
			//return n == 0 ? m : GCD(n, m % n);
		}

	}
