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>
#include<math.h>

int main(){
	unsigned long long int a, b, d;
	unsigned long long int i, j;
	if(a > b){
		d = a;
		a = b;
		b = d;
	}
	while(scanf("%lld %lld", &a, &b) != EOF){
		for(i = b; i <= 200000000; i += b){
			if(i % a != 0) continue;
			break;
		}
		while(b % a != 0){
			if(b % a == 0) break;
			b %= a;
		}
		printf("%lld %lld\n", b, i);
	}
	return 0;
