Note, gcd(x, y, z) means the greatest common divisor of x, y and z, while lcm(x, y, z) means the least common multiple of x, y and z. Note 2, (1, 2, 3) and (1, 3, 2) are two different solutions. Input First line comes an integer T (T <= 12), telling the numbe...

Given two positive integers a and b, we can easily calculate the greatest common divisor (GCD) and the least common multiple (LCM) of a and b. But what about the inverse? That is: given GCD and LCM, finding a and b. Input The input contains multiple test cases, each of which contai...
