Inspired by Project Euler n°204 and Problem 1308 by James
A generalised Hamming number of type n, has no prime factor larger than n.
For example a generalised Hamming number of type 5 has no prime factor larger than 5.
Given a number X, determine how many generalised Hamming numbers n are less than or equal to that number. Please note that 1 counts as a Hamming number.

I like your test suite. Using large X forces a better solution.
Thank you Jonathan. I have discovered this philosophy thanks to James and @bmtran problems.
is there any mathematical algorithm that i dont know about to calculate such big range(10^13)?
i minimized my code as best as i can.still fails for such large number.
why i can't submit my solutions
