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 JAVA (judge verdict: Wrong Answer)

import java.util.Scanner;

public class Main {

	public static void main(String[] args) {

		Scanner stdin = new Scanner(System.in);
		int a = 0;
		int b = 0;
		int ab = 0;
		int r = 0;
		int gcd = 0;
		int lcm = 0;
		int temp = 0;
		while(stdin.hasNext()) {
			a = stdin.nextInt();
			b = stdin.nextInt();
			ab = a * b;

			if(a < b) {
				temp = a;
				a = b;
				b = temp;
			}
			if(a >= b) {
				do {
					r = a % b;
					if(r == 0) {
						break;
					} else {
						a = b;
						b = r;
					}
				}while(r != 1);
				gcd = b;
				lcm = ab / b;
				System.out.println(gcd + " " + lcm);

			}
		}
	}
