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(a,b)
	gcd(b,a) if b > a
	return b if (r = a%b) == 0
	gcd(b,r)
end
def lcm(a,b)
	a * b / gcd(a,b)
end

while line = gets
	a, b = line.split.map(&:to_i)
	puts "#{gcd(a,b)} #{lcm(a,b)}"
end
