Divisibility Rule of 663
The divisibility rule is a way to find out 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 663.
What is the Divisibility Rule of 663?
The divisibility rule for 663 is a method by which we can find out if a number is divisible by 663 or not without using the division method.
Check whether 1989 is divisible by 663 with the divisibility rule.
Step 1: Check if the number is divisible by 3. Add the digits of the number; in 1989, the sum is 1+9+8+9=27, which is divisible by 3.
Step 2: Check if the number is divisible by 221 (which is 663 divided by 3). Use the division method or other divisibility rules to check this.
Step 3: If both conditions are satisfied, the number is divisible by 663.
Tips and Tricks for Divisibility Rule of 663
Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 663.
- Know the multiples of 663: Memorize the multiples of 663 (663, 1326, 1989, 2652...etc.) to quickly check the divisibility. If the number is a multiple of 663, then it is divisible by 663.
- Break it down: Since 663 = 3 × 221, check divisibility by both 3 and 221. This can simplify the process.
Common Mistakes and How to Avoid Them in Divisibility Rule of 663
The divisibility rule of 663 helps us quickly check if a given number is divisible by 663, but common mistakes like calculation errors can lead to incorrect conclusions. Here we will understand some common mistakes that will help you to avoid them.
Mistake 1
Not checking divisibility by both 3 and 221.
Ensure to check both conditions as 663 is the product of these numbers.
