"An integer b is divisible by a nonzero integer a if and only if there exists an integer q such that b = aq. An integer n > 1 is said to be prime if its only divisors are ± 1 and ± n; otherwise, we say that n is composite. If a positive integer n is composite, it has a proper divisor d that satisfies the inequality 1 < d < n. Exercise 5.3.1 " - Divisible by discrete math
