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: Time Limit Exceeded)

#include <stdio.h>

int main(void)
{
	long long int a, b, i, GCD, LCM;
	while (scanf("%d %d", &a, &b) != -1){
		LCM = b;
		while (LCM % a != 0){
			LCM = LCM + b;
		}
		i = 2;
		while ((a % GCD != 0)||(b % GCD != 0)){
			GCD = a / i;
			i++;
		}
	printf("%ld %ld\n", GCD, LCM);
	}
	return 0;
}
