 Description
 In sixth grade, students are presented with different ways to calculate the Least Common Multiple (LCM) and the Greatest Common Factor (GCF) of two integers. The LCM of two integers a and b is the smallest positive integer that is a multiple of both a and b. The GCF of two nonzero integers a and b is the largest positive integer that divides both a and b without remainder.
For this problem you will write a program that determines both the LCM and GCF for positive
integers.
 Input
 The first line of input contains a single integer N, (1 ≤ N ≤ 1000) which is the number of data sets that follow. Each data set consists of a single line of input containing two positive integers, a and b, (1 ≤ a,b ≤ 1000) separated by a space.
 Output
 For each data set, you should generate one line of output with the following values: The data set number as a decimal integer (start counting at one), a space, the LCM, a space, and the GCF.
