Divisibility Rule of 233
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 233.
What is the Divisibility Rule of 233?
The divisibility rule for 233 is a method by which we can find out if a number is divisible by 233 or not without using the division method. Check whether 466 is divisible by 233 with the divisibility rule.
Step 1: Multiply the last digit of the number by 7 (a key component of 233), here in 466, 6 is the last digit, multiply it by 7. 6 × 7 = 42.
Step 2: Subtract the result from Step 1 from the remaining values but do not include the last digit. i.e., 46 - 42 = 4.
Step 3: As it is shown that 4 is not a multiple of 233, therefore, the number is not divisible by 233. If the result from step 2 is a multiple of 233, then the number is divisible by 233.
Tips and Tricks for Divisibility Rule of 233
Learn the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 233.
Know the multiples of 233:
Memorize the multiples of 233 (233, 466, 699, 932, etc.) to quickly check the divisibility. If the result from the subtraction is a multiple of 233, then the number is divisible by 233.
Use the negative numbers:
If the result we get after the subtraction is negative, we will avoid the symbol and consider it as positive for checking the divisibility of a number.
Repeat the process for large numbers:
Students should keep repeating the divisibility process until they reach a small number that is divisible by 233.
For example: Check if 932 is divisible by 233 using the divisibility test.
Multiply the last digit by 7, i.e., 2 × 7 = 14.
Subtract the remaining digits excluding the last digit by 14, 93 - 14 = 79.
Repeat the process: Multiply the last digit of 79 by 7, i.e., 9 × 7 = 63.
Subtract the remaining digits excluding the last digit by 63, 7 - 63 = -56.
As 56 is not a multiple of 233, 932 is not divisible by 233.
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 233
The divisibility rule of 233 helps us to quickly check if the given number is divisible by 233, but common mistakes like calculation errors lead to incorrect calculations. Here we will understand some common mistakes that will help you to understand.
Mistake 1
Not following the correct steps.
Students should follow the correct steps that are multiplying the last digit by 7 and then subtracting the result from the remaining digits excluding the last digit and checking whether it is a multiple of 233.
Mistake 2
Including the last digit in subtraction.
Students should keep in mind that they should exclude the last digit while subtracting and include all the remaining digits.
Mistake 3
Not repeating the process when the result is large.
Students often stop the process after they have got a large number to result in after subtraction. The process should be repeated until we get the smallest number that is divisible by 233.
Mistake 4
Not considering the negative values.
Students consider the negative values thinking divisibility rules don't apply to the negative values. But the divisibility rule is applicable for negative values too. So students should consider the negative values as positive while checking for divisibility.
Mistake 5
Confusing the steps
Students often confuse the steps or forget the steps, to avoid the error students should practice regularly.
Divisibility Rule of 233 Examples
Problem 1
Is 466 divisible by 233?
Yes, 466 is divisible by 233.
Explanation
To check if 466 is divisible by 233, we can use direct division since 233 is a prime number.
1) Divide 466 by 233, which results in 2.
2) Since the division results in a whole number without a remainder, 466 is divisible by 233.
Problem 2
Check the divisibility rule of 233 for 699.
Yes, 699 is divisible by 233.
Explanation
To verify if 699 is divisible by 233, follow these steps:
1) Divide 699 by 233, resulting in exactly 3.
2) Since 3 is a whole number and there is no remainder, 699 is divisible by 233.
Problem 3
Is 2330 divisible by 233?
Yes, 2330 is divisible by 233.
Explanation
To determine if 2330 is divisible by 233:
1) Divide 2330 by 233, which equals 10.
2) The division results in a whole number without a remainder, so 2330 is divisible by 233.
Problem 4
Can 500 be divisible by 233 following the divisibility rule?
No, 500 isn't divisible by 233.
Explanation
To check if 500 is divisible by 233, perform the following:
1) Divide 500 by 233, which results in approximately 2.1459.
2) Since the result is not a whole number, 500 is not divisible by 233.
Problem 5
Check the divisibility rule of 233 for 932.
Yes, 932 is divisible by 233.
Explanation
To check if 932 is divisible by 233:
1) Divide 932 by 233, which equals 4.
2) The division results in a whole number without a remainder, so 932 is divisible by 233.
