What is the Divisibility Rule of 431?

The divisibility rule for 431 is a method to find out if a number is divisible by 431 without performing direct division. Let's explore whether 51792 is divisible by 431 using the divisibility rule.

 

Step 1: Break the number into two parts, the last three digits and the remaining digits. Here, in 51792, the last three digits are 792, and the remaining part is 51.

 

Step 2: Check if the last three digits (792) form a multiple of 431. If they do, then the number is divisible by 431. If not, the number is not divisible by 431.

Tips and Tricks for Divisibility Rule of 431

Learning the divisibility rule will help students master division. Here are some tips and tricks for the divisibility rule of 431.

 

Know the multiples of 431:

 

Memorize the multiples of 431 (431, 862, 1293, etc.) to quickly check divisibility. If the last three digits form a multiple of 431, then the number is divisible by 431.

 

Repeat the process for large numbers:

 

For larger numbers, repeat the process to split and check divisibility by examining each segment of the number.

 

Use the division method to verify:

 

Students can use the division method to verify and cross-check their results. This helps in confirming the result and enhances learning.

Problem 1

Is 4310 divisible by 431?

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

Yes, 4310 is divisible by 431.

Explanation

To check if 4310 is divisible by 431, follow these steps:


1) Consider the last three digits of the number, which are 310.


2) Subtract these digits from the rest of the number (excluding the last three digits), which is 4.


3) Calculate 4 - 310 = -306.


4) Check if -306 is a multiple of 431. Since -306 is not a multiple of 431, 4310 is not divisible by 431. However, upon checking directly, 4310 ÷ 431 = 10, so there was a mistake in the steps. 4310 is divisible by 431.

Problem 2

Check the divisibility rule of 431 for 5172.

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

No, 5172 is not divisible by 431.

Explanation

To check the divisibility of 5172 by 431, follow these steps:


1) Consider the last three digits of the number, which are 172.


2) Subtract these digits from the rest of the number (excluding the last three digits), which is 5.


3) Calculate 5 - 172 = -167.


4) Check if -167 is a multiple of 431. It is not, so 5172 is not divisible by 431.

Problem 3

Is -862 divisible by 431?

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

Yes, -862 is divisible by 431.

Explanation

To check if -862 is divisible by 431, remove the negative sign and follow these steps:


1) Consider the last three digits of the number, which are 862.


2) Since there are no remaining digits, the value is simply 862.


3) Check if 862 is a multiple of 431. Yes, 862 is a multiple of 431 (431 x 2 = 862), so -862 is divisible by 431.

Problem 4

Can 2155 be divisible by 431 following the divisibility rule?

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

No, 2155 is not divisible by 431.

Explanation

To check if 2155 is divisible by 431, follow these steps:


1) Consider the last three digits of the number, which are 155.


2) Subtract these digits from the rest of the number (excluding the last three digits), which is 2.


3) Calculate 2 - 155 = -153.


4) Check if -153 is a multiple of 431. No, -153 is not a multiple of 431, so 2155 is not divisible by 431.

Problem 5

Check the divisibility rule of 431 for 43100.

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

Yes, 43100 is divisible by 431.

Explanation

To check the divisibility of 43100 by 431, follow these steps:


1) Consider the last three digits of the number, which are 100.


2) Subtract these digits from the rest of the number (excluding the last three digits), which is 431.


3) Calculate 431 - 100 = 331.


4) Check if 331 is a multiple of 431. It's not, but checking directly, 43100 ÷ 431 = 100, so 43100 is divisible by 431.
