Some numbers have the property to be divisible by 2 and 3. Other smaller subset of numbers have the property to be divisible by 2, 3 and 5. Another subset with less abundant numbers may be divisible by 2, 3, 5 and 7. These numbers have something in common: their prime factors are contiguous primes.
Create a function count_specMult() that finds the amount of numbers that have the first n primes as factors below a given value, maxVal
Let's see some cases:
count_specMult(3, 200) -------> 6
/// the first 3 primes are 2, 3 and 5
and the found numbers below 200 are 30 < 60 < 90 < 120 < 150 < 180 < 200 (6 numbers)
