Factorizer
Factorizer may be used:
(1) to get the prime decomposition of all numbers in a range of numbers
(2) to get all factors of a single number or all factors of all numbers in a range
(3) to find only the prime numbers in a range of numbers
(4) to find pairs of prime numbers (e.g. 107 and 109) in a certain range
(5) to count (without displaying) the prime numbers in a range of numbers
(6) to find Fermat and Mersenne primes < 2,147,483,647
