Divisors, Prime Factors and Radical of a Natural Number

A calculator, that finds every divisor, prime factor, distinct prime factor and the radical of a positive integer. Also the amount of divisors and prime factors will be counted. Divisors are those natural numbers, by which a positive integer can be divided without rest. For prime numbers, this is 1 and the number itself, other numbers have further divisors. Prime factors are those prime numbers which multiplicated with each other give the orininal number. The radical of a positive integer, a term from number theory, is the product of the distinct prime factors.

Example: the number 123456 has 28 divisors and 8 prime factors, 3 of those different. Its radical is 3858.
