Divisibility Rule of 603

Professor Greenline Explaining Math Concepts

The divisibility rule is a way to determine whether a number is divisible by another number without using the division method. In real life, we can use the divisibility rule for quick math, dividing things evenly, and sorting things. In this topic, we will learn about the divisibility rule of 603.

What is the Divisibility Rule of 603?

The divisibility rule for 603 is a method by which we can find out if a number is divisible by 603 or not without using the division method. Let's check whether 1809 is divisible by 603 with the divisibility rule.

Step 1: Check if the number is divisible by both 3 and 201 (since 603 = 3 × 201).
Step 2: For divisibility by 3, sum the digits of the number. If the sum is divisible by 3, then the number is divisible by 3. For 1809, sum the digits: 1 + 8 + 0 + 9 = 18. Since 18 is divisible by 3, 1809 is divisible by 3.
Step 3: For divisibility by 201, break it down further. Check divisibility by 3 (already done) and 67 (since 201 = 3 × 67). Use the divisibility rule for 67, which is more complex and requires direct division or checking known multiples.
Step 4: If a number passes both divisibility tests (for 3 and 67), it is divisible by 603.

Tips and Tricks for Divisibility Rule of 603

Understanding the divisibility rule will help in mastering division. Let’s learn a few tips and tricks for the divisibility rule of 603.

Know the multiples of 603: Memorize some multiples of 603 (603, 1206, 1809, etc.) to quickly check divisibility.
 

Use the division method for complex parts: Since 603 includes a less straightforward factor like 67, sometimes direct division may be necessary.
