This problem is a programming version of Problem 204 from projecteuler.net
A Hamming number is a positive number which has no prime factor larger than .
So the first few Hamming numbers are , , , , , , , , , , .
There are Hamming numbers not exceeding .
We will call a positive number a generalised Hamming number of type , if it has no prime factor larger than .
Hence the Hamming numbers are the generalised Hamming numbers of type .
How many generalised Hamming numbers of type are there which don't exceed ?
The only line of each test file contains two integer numbers separated by a single space: and .
Print exactly one number: the number of generalised Hamming numbers of type which don't exceed .
