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 818.

What is the Divisibility Rule of 818?

The divisibility rule for 818 is a method by which we can find out if a number is divisible by 818 or not without using the division method. Check whether 1636 is divisible by 818 with the divisibility rule.

Step 1: Identify the number formed by the last three digits of the number, here in 1636, 636 is the number formed by the last three digits.

Step 2: Check if 636 is divisible by 818. Since 636 is not a multiple of 818, the number 1636 is not divisible by 818.

Tips and Tricks for Divisibility Rule of 818

Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 818.

Know the multiples of 818:


Memorize the multiples of 818 (818, 1636, 2454, 3272, etc.) to quickly check divisibility. If the last three digits form a number that is a multiple of 818, then the overall number is divisible by 818.

Repeat the process for large numbers:


Students should keep repeating the divisibility process until they reach a small number that is divisible by 818. 

For example: Check if 3272 is divisible by 818 using the divisibility test.
Identify the last three digits: 272.
Since 272 is not a multiple of 818, 3272 is not divisible by 818.

Use the division method to verify:


Students can use the division method as a way to verify and crosscheck their results. This will help them to verify and also learn.

Common Mistakes and How to Avoid Them in Divisibility Rule of 818

Problem 1

Is 3272 divisible by 818?

Okay, lets begin

Yes, 3272 is divisible by 818.
 

Explanation

Let's apply the divisibility rule for 818.


1) Multiply the last two digits of the number by 2, 72 × 2 = 144.


2) Subtract the result from the remaining digits excluding the last two digits, 32 – 144 = -112.


3) Check if the result is a multiple of 818. Since -112 is not directly a multiple of 818, we verify by division: 3272 ÷ 818 = 4. Therefore, 3272 is divisible by 818.

Problem 2

Check the divisibility rule of 818 for 6552.

Okay, lets begin

Yes, 6552 is divisible by 818.
 

Explanation

To check if 6552 is divisible by 818:


1) Multiply the last two digits by 2, 52 × 2 = 104.


2) Subtract the result from the remaining digits, excluding the last two digits, 65 – 104 = -39.


3) Check if -39 is a multiple of 818. By division, 6552 ÷ 818 = 8. Therefore, 6552 is divisible by 818.

Problem 3

Is -4090 divisible by 818?

Okay, lets begin

No, -4090 is not divisible by 818.
 

Explanation

To determine if -4090 is divisible by 818:


1) Multiply the last two digits by 2, 90 × 2 = 180.


2) Subtract the result from the remaining digits excluding the last two digits, 40 – 180 = -140.

3) Check if -140 is a multiple of 818. By division, -4090 ÷ 818 does not result in an integer, so -4090 is not divisible by 818.

Well explained 👍

Problem 4

Can 2454 be divisible by 818 following the divisibility rule?

Okay, lets begin

No, 2454 isn't divisible by 818.
 

Explanation

To check if 2454 is divisible by 818:


1) Multiply the last two digits by 2, 54 × 2 = 108.


2) Subtract the result from the remaining digits excluding the last two digits, 24 – 108 = -84.


3) Check if -84 is a multiple of 818. By direct division, 2454 ÷ 818 does not yield an integer, so 2454 is not divisible by 818.

Well explained 👍

Problem 5

Check the divisibility rule of 818 for 8180.

Okay, lets begin

Yes, 8180 is divisible by 818.
 

Explanation

To verify divisibility of 8180 by 818:


1) Multiply the last two digits by 2, 80 × 2 = 160.


2) Subtract the result from the remaining digits excluding the last two digits, 81 – 160 = -79.


3) Check if -79 is a multiple of 818. Division confirms: 8180 ÷ 818 = 10. Thus, 8180 is divisible by 818.
