Graham's function (named for Ronald L. Graham, director of research at
AT&T Bell Labs) of a positive integer n is computed as follows: Find
an increasing sequence of integers a0, a1, ..., a_k such that
1. a0 = n
2. The product of the integers is a perfect square
3. a_k is as small as possible.
Then G(n) = a_k.
Write a function, 'Graham', which, given a positive integer n, returns G(n)
