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)

import scala.io.Source.stdin

object Main extends App {
  def gcd(m:Long,n:Long):Long = if(n==0) m else gcd(n, m % n)

  println {
    {
      for(s <- stdin.getLines.map(_.split(" ").map(_.toLong))) yield {
          val g = gcd(s(0),s(1))
          g + " " + (s(0)*s(1)/g)
      }
    }.mkString("\n")
  }
}
