Divisibility Rule of 229
The divisibility rule is a way to determine whether a number is divisible by another number without performing the full division. In practical applications, divisibility rules help with quick calculations, even distribution, and organization. In this topic, we will explore the divisibility rule of 229.
What is the Divisibility Rule of 229?
The divisibility rule for 229 allows us to find out if a number is divisible by 229 without using the division method. Let's check whether 4580 is divisible by 229 using this rule.
Step 1: Multiply the last digit of the number by a specific factor related to 229. Here, for simplicity, let's assume a hypothetical factor (as a specific factor for 229 isn’t straightforward like smaller primes).
Step 2: Subtract the result from Step 1 from the remaining digits, not including the last digit. For example, assume we multiply the last digit, 0, by 1 (since any number times 0 is 0), and subtract from 458.
Step 3: If the result from Step 2 is a multiple of 229, then the original number is divisible by 229. If not, it isn’t divisible by 229.
Tips and Tricks for Divisibility Rule of 229
Understanding the divisibility rule can help in mastering division. Here are some tips and tricks for the divisibility rule of 229:
Know the multiples of 229:
Memorize multiples of 229 (229, 458, 687, 916, etc.) to quickly check divisibility. If the subtraction result is a multiple of 229, the number is divisible by 229.
Use the negative numbers:
If the subtraction result is negative, consider it as positive for checking divisibility.
Repeat the process for large numbers:
For large numbers, repeat the divisibility process until you reach a smaller number that is divisible by 229.
Use the division method to verify:
Employ the division method to verify and cross-check results. This aids in verification and learning.
Common Mistakes and How to Avoid Them in Divisibility Rule of 229
The divisibility rule of 229 helps us quickly check if a number is divisible by 229. However, common mistakes like calculation errors can lead to incorrect conclusions. Here we outline some mistakes and their solutions.
Mistake 1
Not following the correct steps.
Follow the steps correctly, starting with multiplying the last digit and subtracting it from the remaining digits.
Mistake 2
Including the last digit in subtraction.
Exclude the last digit while subtracting and include all other digits.
Mistake 3
Not repeating the process when the result is large.
Continue the process until you achieve a small number that is divisible by 229.
Mistake 4
Not considering the negative values.
Consider negative values as positive when checking for divisibility.
Mistake 5
Confusing the steps.
Practice regularly to avoid confusion and remember the steps.
Divisibility Rule of 229 Examples
Problem 1
Is 6875 divisible by 229?
No, 6875 is not divisible by 229.
Explanation
To check if 6875 is divisible by 229, follow these steps:
1) Multiply the last two digits (75) by 3, resulting in 225.
2) Subtract this result from the remaining leading digits (68), 68 - 225 = -157.
3) Since -157 is not a multiple of 229, 6875 is not divisible by 229.
Problem 2
Check the divisibility rule of 229 for the number 1832.
Yes, 1832 is divisible by 229.
Explanation
To check the divisibility rule of 229 for 1832:
1) Multiply the last two digits (32) by 3, resulting in 96.
2) Subtract this result from the remaining digits (18), 18 - 96 = -78.
3) Since -78 is a multiple of 229 (229 x -1 + 151 = -78), 1832 is divisible by 229.
Problem 3
Is -4580 divisible by 229?
No, -4580 is not divisible by 229.
Explanation
To check the divisibility of -4580 by 229:
1) Remove the negative sign and consider 4580.
2) Multiply the last two digits (80) by 3, resulting in 240.
3) Subtract this result from the remaining digits (45), 45 - 240 = -195.
4) Since -195 is not a multiple of 229, -4580 is not divisible by 229.
Problem 4
Can 9172 be divisible by 229 following the divisibility rule?
Yes, 9172 is divisible by 229.
Explanation
To check if 9172 is divisible by 229:
1) Multiply the last two digits (72) by 3, resulting in 216.
2) Subtract this result from the remaining digits (91), 91 - 216 = -125.
3) Since -125 is not a multiple of 229, 9172 is not divisible by 229.
Problem 5
Check the divisibility rule of 229 for 2290.
Yes, 2290 is divisible by 229.
Explanation
To check the divisibility rule for 2290:
1) Multiply the last two digits (90) by 3, resulting in 270.
2) Subtract this result from the remaining digits (22), 22 - 270 = -248.
3) Since -248 is a multiple of 229 (229 x -1 + 19 = -248), 2290 is divisible by 229.
