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 Scala (judge verdict: Accepted)

object Main {

  def gcd(a: Long, b: Long): Long = if(b!=0) gcd(b,a%b) else a

  def lcm(a: Long, b: Long): Long = a * b / gcd(a,b)

  def loop(s: String):Unit = if(s != null){
    val Array(a,b,_*) = s.split(" ").map(_.toLong)
    println(gcd(a,b)+" "+lcm(a,b))
    loop(scala.io.StdIn.readLine)
  }

  def main(args: Array[String]): Unit = {
    loop(scala.io.StdIn.readLine)
  }
}
