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 gcd(x, y)
  r = x % y
  return y if r == 0
  gcd(y, r)
end

# ?????§??¬?????°
def lcm(x, y, gcd)
  return (x * y) / gcd
end

array = []
while line = gets do
  x, y = line.split.map(&:to_i)
  gcd = gcd(x, y)
  lcm = lcm(x, y, gcd)
  puts "#{gcd} #{lcm}"
end
