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)
{
    int a,b;
    int i,x=0;
    while(scanf("%d",&a)!=EOF){
    scanf("%d%d",&a,&b);
    for(i=1;i<=a;i++){
        if(a%i==0 && b%i==0){
            x=i;
        }
    }
    printf("%d %d\n",x,a*b/x);
    }
    return 0;
}
