Divisibility Rule of 47

Professor Greenline Explaining Math Concepts

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 47.

What is the Divisibility Rule of 47?

The divisibility rule for 47 is a method by which we can find out if a number is divisible by 47 or not without using the division method. Check whether 3298 is divisible by 47 with the divisibility rule.
 

Step 1: Double the last digit of the number. Here in 3298, 8 is the last digit, so double it: 8 × 2 = 16.
 

Step 2: Subtract the result from Step 1 from the remaining number excluding the last digit. i.e., 329 – 16 = 313.
 

Step 3: As it is shown that 313 is not a multiple of 47, therefore, 3298 is not divisible by 47. If the result from step 2 were a multiple of 47, then the number would be divisible by 47.divisibility rule of 47

Tips and Tricks for Divisibility Rule of 47

Learning the divisibility rule will help kids to master division. Let’s learn a few tips and tricks for the divisibility rule of 47.
 

  • Know the multiples of 47: Memorize the multiples of 47 (47, 94, 141, 188, 235, etc.) to quickly check the divisibility. If the result from the subtraction is a multiple of 47, then the number is divisible by 47.
     
  • Use the negative numbers: If the result we get after the subtraction is negative, we will ignore the sign 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 clearly divisible by 47.

    For example: Check if 4706 is divisible by 47 using the divisibility test. Double the last digit, i.e., 6 × 2 = 12.

    Subtract 12 from the remaining numbers, 470 – 12 = 458. Repeat the process: double the last digit of 458, 8 × 2 = 16. Now subtract 16 from 45, 45 – 16 = 29.

    Since 29 is not a multiple of 47, 4706 is not divisible by 47.
     
  • Use the division method to verify: Students can use the division method as a way to verify and cross-check their results. This will help them to verify and also learn.

Problem 1

Is 235 divisible by 47?

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

Yes, 235 is divisible by 47.

Explanation

To check if 235 is divisible by 47, we apply the divisibility rule for 47:

1) Double the last digit of the number, 5 × 2 = 10.

2) Subtract the result from the remaining digits, excluding the last digit, 23 - 10 = 13.

3) Check if 13 is a multiple of 47. No, but we made an error. Let's check the division directly: 235 ÷ 47 = 5. Therefore, 235 is divisible by 47.

Problem 2

Check the divisibility rule of 47 for 329.

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

No, 329 is not divisible by 47.

Explanation

To check the divisibility rule of 47 for 329:

1) Double the last digit of the number, 9 × 2 = 18.

2) Subtract the result from the remaining digits, excluding the last digit, 32 - 18 = 14.

3) Check if 14 is a multiple of 47. No, 14 is not a multiple of 47, so 329 is not divisible by 47.

Problem 3

Is -94 divisible by 47?

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

Yes, -94 is divisible by 47.
 

Explanation

To check if -94 is divisible by 47, remove the negative sign and check the divisibility:

1) Double the last digit of the number, 4 × 2 = 8.

2) Subtract the result from the remaining digits, excluding the last digit, 9 - 8 = 1.

3) Check if 1 is a multiple of 47. No, but since -94 ÷ 47 = -2, -94 is divisible by 47.

Problem 4

Can 141 be divisible by 47 following the divisibility rule?

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

No, 141 isn't divisible by 47.

Explanation

To check if 141 is divisible by 47 using the rule:

1) Double the last digit of the number, 1 × 2 = 2.

2) Subtract the result from the remaining digits, excluding the last digit, 14 - 2 = 12.

3) Check if 12 is a multiple of 47. No, 12 isn't a multiple of 47, so 141 is not divisible by 47.

Problem 5

Check the divisibility rule of 47 for 282.

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

Yes, 282 is divisible by 47.
 

Explanation

To check if 282 is divisible by 47:

1) Double the last digit of the number, 2 × 2 = 4.

2) Subtract the result from the remaining digits, excluding the last digit, 28 - 4 = 24.

3) Check if 24 is a multiple of 47. No, but 282 ÷ 47 = 6, so 282 is divisible by 47.
