Divisibility Rule of 647

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 647.

What is the Divisibility Rule of 647?

The divisibility rule for 647 is a method by which we can find out if a number is divisible by 647 or not without using the division method. Check whether 1941 is divisible by 647 with the divisibility rule.

 

Step 1: Multiply the last three digits of the number by 3. Here in 1941, 941 is the last three digits, so multiply it by 3. 941 × 3 = 2823.


   
Step 2: Subtract the result from Step 1 from the remaining digits but do not include the last three digits. i.e., 1 - 2823 = -2822.

 

Step 3: Check if the result from Step 2 is a multiple of 647. Since -2822 is not a multiple of 647, 1941 is not divisible by 647.

Tips and Tricks for Divisibility Rule of 647

Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 647.

 

Know the multiples of 647:


Memorize the multiples of 647 (647, 1294, 1941, 2588, etc.) to quickly check divisibility. If the result from subtraction is a multiple of 647, then the number is divisible by 647.

 

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 647. For example: Check if 3882 is divisible by 647 using the divisibility test. Multiply the last three digits by 3, i.e., 882 × 3 = 2646. Subtract the remaining digits excluding the last three digits by 2646, 3 - 2646 = -2643.

 

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 the number of pages in a book, 1294, divisible by 647?

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

Yes, 1294 is divisible by 647.

Explanation

To check if 1294 is divisible by 647, follow these steps:  

1) Divide the number by 647, 1294 ÷ 647 = 2.  

2) The division results in a whole number, so 1294 is divisible by 647.

Problem 2

A cargo ship is transporting 1941 tons of goods. Is the total weight divisible by 647?

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

Yes, 1941 is divisible by 647.

Explanation

To check if 1941 is divisible by 647:  

1) Divide the total weight by 647, 1941 ÷ 647 = 3.  

2) Since the result is a whole number, 1941 is divisible by 647.

Problem 3

A company has a budget of 3235 dollars. Can the budget be evenly divided among 647 employees?

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

No, 3235 is not divisible by 647.

Explanation

To verify the divisibility:  

1) Divide the budget by 647, 3235 ÷ 647 ≈ 5.  

2) The division results in a non-whole number, so 3235 is not divisible by 647.

Problem 4

A marathon event is planned with 647 participants. If each participant needs 5 energy bars, can 3235 energy bars be evenly distributed among them?

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

Yes, 3235 is divisible by 647.

Explanation

To check:  

1) Multiply the number of participants by energy bars needed per participant, 647 × 5 = 3235.  

2) Since the energy bars match the total, 3235 is divisible by 647.

Problem 5

Check if the number 3882 can be equally divided by 647 in a series of transactions.

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

Yes, 3882 is divisible by 647.

Explanation

To determine divisibility:  

1) Divide 3882 by 647, 3882 ÷ 647 = 6.  

2) The result is a whole number, so 3882 is divisible by 647.
