The Trivial Truth: The Smallest Three-Digit Number Divisible by At Least One When posed with the question, “What is the smallest three-digit number divisible by at least one?” the answer may seem obvious—after all, every number is divisible by itself, right? But beneath this seemingly simple query lies an opportunity to explore the fascinating world of divisibility and number theory. Why the Triviality Is Still Interesting At first glance, any three-digit number—starting from 100—is trivially divisible by at least one number. Specifically, 100 is divisible by 1 and 100, fulfilling the requirement effortlessly. However, what makes this question valuable isn’t just its simplicity, but how it opens the door to deeper understanding.
