Divisibility Rule of 439

Professor Greenline Explaining Math Concepts

The divisibility rule is a method to determine if a number is divisible by another number without actually performing the division. In practical scenarios, divisibility rules can be used for quick calculations, equal distribution, and organizing items. In this topic, we will explore the divisibility rule of 439.

What is the Divisibility Rule of 439?

The divisibility rule for 439 is a systematic approach to check if a number is divisible by 439 without performing direct division. Let's check whether 8778 is divisible by 439 using this rule.

 

Step 1: Multiply the last digit of the number by 2. In 8778, 8 is the last digit, so multiply it by 2. 8 × 2 = 16

 

Step 2: Subtract the result from Step 1 from the remaining digits, excluding the last digit. That is, 877–16 = 861.

 

Step 3: Since 861 is not a multiple of 439, the number 8778 is not divisible by 439. If the result from Step 2 were a multiple of 439, then the number would be divisible by 439.divisibility rule of 439

Tips and Tricks for Divisibility Rule of 439

Learning the divisibility rule will help students master division. Here are some tips and tricks for the divisibility rule of 439.

 

  • Know the multiples of 439: Memorize the multiples of 439 (439, 878, 1317...) to quickly check divisibility. If the result from the subtraction is a multiple of 439, then the number is divisible by 439.
     
  • Use negative numbers: If the result after subtraction is negative, ignore the negative sign and consider it as positive for checking divisibility.
     
  • Repeat the process for large numbers: Students should keep repeating the divisibility process until they reach a small number that is divisible by 439. For example, check if 43895 is divisible by 439 using the divisibility test. Multiply the last digit by 2, i.e., 5 × 2 = 10. Subtract the remaining digits excluding the last digit by 10, 4389–10 = 4379. Repeat the process: multiply the last digit by 2, 9 × 2 = 18. Now subtract 18 from the remaining numbers excluding the last digit, 437–18 = 419. As 419 is not a multiple of 439, 43895 is not divisible by 439.
     
  • Use the division method to verify: Students can use the division method to verify and crosscheck their results. This will help them verify and also learn.

Problem 1

Is 2634 divisible by 439?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

Yes, 2634 is divisible by 439.

Explanation

To check the divisibility of 2634 by 439, follow these steps:


1) Multiply the last digit by 3, 4 × 3 = 12.


2) Subtract the result from the remaining digits, excluding the last digit, 263 – 12 = 251.


3) Repeat the process: Multiply the last digit of 251 by 3, 1 × 3 = 3. Subtract it from the remaining digits, 25 – 3 = 22.


4) Since 22 is less than 439 and non-zero, 2634 is not divisible by 439. (This is a corrected explanation; the initial answer in this example was incorrect.)

Problem 2

Check the divisibility rule of 439 for 878.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

No, 878 is not divisible by 439.

Explanation

To determine if 878 is divisible by 439:


1) Multiply the last digit by 3, 8 × 3 = 24.


2) Subtract the result from the remaining digits, 87 – 24 = 63.


3) Since 63 is not zero and less than 439, 878 is not divisible by 439.

Problem 3

Is 0 divisible by 439?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

Yes, 0 is divisible by 439.

Explanation

Any number is divisible by any non-zero integer, including 439, when the number is 0. The rule applies trivially, as 0 divided by any non-zero number is 0.

Problem 4

Can 1744 be divisible by 439 following the divisibility rule?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

No, 1744 is not divisible by 439.

Explanation

To check if 1744 is divisible by 439:


1) Multiply the last digit by 3, 4 × 3 = 12.


2) Subtract the result from the remaining digits, 174 – 12 = 162.


3) 162 is less than 439 and not zero, indicating that 1744 is not divisible by 439.

Problem 5

Check the divisibility rule of 439 for 1317.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

Yes, 1317 is divisible by 439.

Explanation

To verify 1317's divisibility by 439:


1) Multiply the last digit by 3, 7 × 3 = 21.


2) Subtract the result from the remaining digits, 131 – 21 = 110.


3) Repeat the process: Multiply the last digit of 110 by 3, 0 × 3 = 0. Subtract from the remaining digits, 11 – 0 = 11.


4) Since 11 is not zero, 1317 is not divisible by 439. (This is another corrected explanation; the initial answer in this example was incorrect.)
