Write a program which computes the greatest common divisor (GCD) and the least common multiple (LCM) of given `a` and `b`.

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.

- 0 <
`a, b`≤ 2,000,000,000 - LCM(
`a, b`) ≤ 2,000,000,000 - The number of data sets ≤ 50

For each data set, print GCD and LCM separated by a single space in a line.
