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 Ruby (judge verdict: Accepted)

def get_GCD(a, b)
  while ((r = a%b) != 0) do
    a = b
    b = r
  end
  b
end

def get_LCM(a, b, gcd)
  a * b / gcd
end

while s = gets do
  a, b = s.split(/\s/).map(&:to_i).sort

  gcd = get_GCD(a, b)
  lcm = get_LCM(a, b, gcd)
  puts "#{gcd} #{lcm}"
end
