Divisibility Rule of 86

Professor Greenline Explaining Math Concepts

The divisibility rule is a method to determine if a number is divisible by another number without performing actual division. In practical scenarios, we use divisibility rules for quick math, dividing things evenly, and sorting items. Here, we will explore the divisibility rule of 86.

What is the Divisibility Rule of 86?

The divisibility rule for 86 is a technique to verify if a number is divisible by 86 without using direct division. Let's check if 5162 is divisible by 86 using the divisibility rule.

 

Step 1: Split the number into two parts. For 5162, we consider 51 and 62 as two parts.

 

Step 2: Check if each part is divisible by 86. Neither 51 nor 62 is divisible by 86.

 

Step 3: Since neither part is divisible by 86, 5162 is not divisible by 86.divisibility rule of 86

Tips and Tricks for Divisibility Rule of 86

Understanding the divisibility rule can help students master division. Here are some tips and tricks for the divisibility rule of 86:

 

  • Know the multiples of 86: Memorize the multiples of 86 (86, 172, 258, 344, etc.) to quickly recognize divisibility.
     
  • Combine division with estimation: Estimate if larger numbers are close to multiples of 86 to simplify calculations.
     
  • Use smaller numbers: If the number is large, break it down into smaller parts to check each part separately for divisibility by 86.
     
  • Verify using division: Students can use the division method to verify their results, ensuring the divisibility rule was applied correctly.

Problem 1

Is 3444 divisible by 86?

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

Yes, 3444 is divisible by 86.

Explanation

To determine if 3444 is divisible by 86, follow these steps:


1) Separate the number into two parts: the last two digits and the remaining number.


2) The last two digits are 44. Double this to get 88.


3) Subtract the result from the remaining number: 34 - 88 = -54.


4) Check if the absolute value of the result is divisible by 86. 54 is not divisible by 86, but since we subtracted instead of added, we must check the original number directly. 3444 divided by 86 equals 40, a whole number, so it is divisible.

Problem 2

Check the divisibility rule of 86 for 7742.

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

Yes, 7742 is divisible by 86.

Explanation

To check if 7742 is divisible by 86:


1) Isolate the last two digits: 42.


2) Double these to get 84.


3) Subtract 84 from the remaining number: 77 - 84 = -7.


4) Since -7 is not divisible by 86, verify directly. 7742 divided by 86 equals 90, confirming divisibility.

Problem 3

Is 5168 divisible by 86?

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

No, 5168 is not divisible by 86.

Explanation

To see if 5168 is divisible by 86:


1) Take the last two digits: 68.


2) Double them to get 136.


3) Subtract from the remaining digits: 51 - 136 = -85.


4) Since -85 is not divisible by 86, and direct division confirms, 5168 is not divisible by 86.

Problem 4

Can 602 be divisible by 86 following the divisibility rule?

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

No, 602 isn't divisible by 86.

Explanation

To determine if 602 is divisible by 86:


1) Look at the last two digits: 02.


2) Double them to get 4.


3) Subtract from the remaining digits: 6 - 4 = 2.


4) Since 2 is not divisible by 86, and direct division confirms, 602 is not divisible by 86.

Problem 5

Check the divisibility rule of 86 for 6884.

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

Yes, 6884 is divisible by 86.

Explanation

To verify if 6884 is divisible by 86:


1) Isolate the last two digits: 84.


2) Double them to get 168.


3) Subtract from the remaining number: 68 - 168 = -100.


4) Since direct division shows 6884 divided by 86 equals 80, it is divisible.
