Write a program which computes the greatest common divisor (GCD) and the least common multiple (LCM) of given a and b (0 < a, b ≤ 2,000,000,000). You can supporse that LCM(a, b) ≤ 2,000,000,000.
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.
For each data set, print GCD and LCM separated by a single space in a line.
