Alternatively, perhaps the problem meant: divisible by **one** of them, but says “andâ€â€”highlighting shared constraint.

Understanding Divisibility: When a Number Is Divisible by One of Them — and Why Shared Constraints Matter When solving math problems involving divisibility, a common challenge arises: determining whether a number is divisible by one of several given divisors, yet expressing it formally often requires emphasizing shared mathematical constraints. Instead of vague or isolated checks, effective problem-solving focuses on the shared divisibility condition—the underlying rule that links divisors through a flexible yet precise logical framework. ### What Does “Divisible by One of Them” Really Mean? At its core, saying a number n is divisible by one of a set of divisors—say, {2, 3, 5}—means n is divisible by at least one, but not necessarily all. This subtle but important distinction shifts how we frame the problem: rather than demanding strict mutual exclusivity, we identify overlapping or shared modular properties.
