How to know how many divisors a number has?
Fortunately, there is a quick and accurate method that uses either the divisor or the tau function. Let d(n) be the number of divisors of a natural number n. We start by writing the number as the product of prime factors: n = p a q b r c … then the number of divisors, d (n) = (a + 1) (b + 1) (c + 1) …

Is zero the divisor of all numbers?
1 and 1 divide (are factors of) every integer, every integer is divisible by itself, and every integer divides 0 except, by convention, 0 itself (see also division by zero). Numbers that are divisible by 2 are called even, and numbers that are not divisible by 2 are called odd.
