Divisibility Rule of 447
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 447.
What is the Divisibility Rule of 447?
The divisibility rule for 447 is a method by which we can find out if a number is divisible by 447 or not without using the division method. Check whether 1341 is divisible by 447 with the divisibility rule.
Step 1: Multiply the last digit of the number by 2. Here in 1341, 1 is the last digit, so multiply it by 2. 1 × 2 = 2
Step 2: Subtract the result from Step 1 from the remaining values but do not include the last digit. i.e., 134 - 2 = 132.
Step 3: As it is shown that 132 is a multiple of 447, therefore, the number is divisible by 447. If the result from step 2 isn't a multiple of 447, then the number isn't divisible by 447.
Tips and Tricks for Divisibility Rule of 447
Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 447.
- Know the multiples of 447: Memorize the multiples of 447 (447, 894, 1341, 1788, 2235…etc.) to quickly check the divisibility. If the result from the subtraction is a multiple of 447, then the number is divisible by 447.
- 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 447. For example, check if 4023 is divisible by 447 using the divisibility test. Multiply the last digit by 2, i.e., 3 × 2 = 6. Subtract the remaining digits excluding the last digit by 6, 402 - 6 = 396. Still, 396 is a large number, hence we will repeat the process again and multiply the last digit by 2, 6 × 2 = 12. Now subtracting 12 from the remaining numbers excluding the last digit, 39 - 12 = 27. As 27 is a multiple of 447, 4023 is divisible by 447.
- 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 447
The divisibility rule of 447 helps us to quickly check if the given number is divisible by 447, but common mistakes like calculation errors lead to incorrect results. 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 with 2 and then subtracting the result from the remaining digits excluding the last digits and checking whether it is a multiple of 447.
