In order to make the divisible by  claim in general, you must define the Natural numbers as the positive integers. Your premise is generally false given that it is possible for the set of Natural numbers to have 0 as an element. See Wikipedia: In mathematics, a natural number is either a positive integer (1, 2, 3, 4, …) or a non-negative integer (0, 1, 2, 3, 4, …). The former definition is generally used in number theory, while the latter is preferred in set theory and computer science.
