Understanding the Concept of Divisibility with the Largest 3-Digit Number Divisible by 333

Divisibility, in the context of number theory and mathematics, often comes up in various problems and applications. This article aims to explain the logic and steps to find the largest 3-digit number that is exactly divisible by 333. Whether you are a student, teacher, or any math enthusiast, this guide will help you solve similar problems and improve your understanding of divisibility rules. Let's dive into the process step-by-step.

Introduction to Divisibility and the Problem at Hand

The largest 3-digit number is 999. To determine which of these numbers is exactly divisible by 333, we employ a simple division method. The goal is to find the quotient when 999 is divided by 333, and then use that quotient to find the largest multiple of 333 that remains a 3-digit number. This process will involve arithmetic operations, but it is straightforward when broken down.

Step-by-Step Process of Finding the Largest 3-Digit Number Divisible by 333

Here’s how we can systematically find the largest 3-digit number that is exactly divisible by 333:

Step 1: Identify the Largest 3-Digit Number

The largest 3-digit number is 999. This forms the basis of our problem and is the starting point for our calculation.

Step 2: Divide 999 by 333

Next, we divide 999 by 333 to see how many times 333 fits into 999 without resulting in a remainder. The division can be written as:

999 ÷ 333 ≈ 3

Step 3: Determine the Quotient and Use It

The quotient from the division is 3, which means 333 goes into 999 exactly 3 times. To find the largest 3-digit number that is a multiple of 333, we multiply 333 by this quotient:

333 × 3 999

Conclusion and Verification

Thus, 999 is both a 3-digit number and precisely divisible by 333, confirming it as the largest 3-digit number that fits our criteria. We have successfully demonstrated the process of finding such numbers, which can be applied to other large divisors or different types of divisibility questions.
