Divisibility Rule of 818
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
The divisibility rule of 818 helps us quickly check if a given number is divisible by 818, but common mistakes, like calculation errors, lead to incorrect results. Here, we will understand some common mistakes that will help you to avoid them.
Mistake 1
Not following the correct steps.
Students should follow the correct steps by identifying the last three digits and checking if they form a multiple of 818.
Mistake 2
Forgetting to check the last three digits.
Always focus on the last three digits of the number to determine divisibility.
Mistake 3
Not repeating the process when the result is large.
Students often stop the process after they have a large number. The process should be repeated until you get the smallest number that is divisible by 818.
Mistake 4
Confusing the steps.
Students often confuse the steps or forget them. To avoid this error, students should practice regularly.
Mistake 5
Not considering the negative values.
Students might ignore negative values thinking divisibility rules don't apply to negative numbers. But the divisibility rule is applicable for negative values too. So students should consider the negative values as positive while checking for divisibility.
Divisibility Rule of 818 Examples
Problem 1
Is 3272 divisible by 818?
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.
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?
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.
Problem 4
Can 2454 be divisible by 818 following the divisibility rule?
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.
Problem 5
Check the divisibility rule of 818 for 8180.
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.
