What is the Divisibility Rule of 657?

The divisibility rule for 657 helps determine if a number is divisible by 657 without using division. Let's check whether 1971 is divisible by 657 using the divisibility rule.

 

Example:

 

Step 1: Find the sum of the digits of the number. For 1971, the sum is 1 + 9 + 7 + 1 = 18.

 

Step 2: Check if this sum, 18, is divisible by 3 (since 657 is divisible by 3), which it is.

 

Step 3: Also, check if the number is divisible by 219 (since 657 = 3 × 219). For 1971, perform 1971 ÷ 219 = 9.

 

Step 4: Since 1971 is divisible by both 3 and 219, it is divisible by 657.divisibility rule of 657

Tips and Tricks for Divisibility Rule of 657

Understanding the divisibility rule will help students master division. Here are some tips and tricks for the divisibility rule of 657.

 

  • Know the factors: Memorize the factors of 657, which are 3 and 219. If a number is divisible by both, it is divisible by 657.
     
  • Use the sum of digits: If the sum of the digits of a number is divisible by 3, the number is divisible by 3, a factor of 657.
     
  • Repeat the process for large numbers: For larger numbers, continue breaking them down using these factors until you reach a smaller, more manageable number.
     
  • Use division for verification: As a cross-check, use traditional division to verify that the number is indeed divisible by 657.

Problem 1

Is 1971 divisible by 657?

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

Yes, 1971 is divisible by 657.

Explanation

To check if 1971 is divisible by 657, follow these steps:  


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


2) Add the result to the remaining digits excluding the last digit, 197 + 3 = 200.  


3) Check if 200 is a multiple of 657. Since 200 is not a multiple of 657, we repeat the process.  


4) For larger numbers, the result is still not divisible, but combining steps and checking known multiples, 1971 is divisible by 657 (657 x 3 = 1971).

Problem 2

Check the divisibility rule of 657 for 52656.

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

Yes, 52656 is divisible by 657. 

Explanation

To check the divisibility rule of 657 for 52656:  


1) Multiply the last digit by 3, 6 × 3 = 18.  


2) Add the result to the remaining digits excluding the last digit, 5265 + 18 = 5283.  


3) Check if 5283 is a multiple of 657. Since 5283 is exactly 657 x 8, it is divisible by 657.

Problem 3

Is -3942 divisible by 657?

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

No, -3942 is not divisible by 657.

Explanation

To check if -3942 is divisible by 657:  


1) Multiply the last digit by 3, 2 × 3 = 6.  


2) Add the result to the remaining digits excluding the last digit, 394 + 6 = 400.  


3) Check if 400 is a multiple of 657. No, 400 is not a multiple of 657.

Problem 4

Can 1314 be divisible by 657 following the divisibility rule?

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

Yes, 1314 is divisible by 657. 

Explanation

To check if 1314 is divisible by 657:  


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

 
2) Add the result to the remaining digits excluding the last digit, 131 + 12 = 143.

 
3) Check if 143 is a multiple of 657. Since 1314 is exactly 657 x 2, it is divisible by 657.

Problem 5

Check the divisibility rule of 657 for 13140.

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

No, 13140 is not divisible by 657.

Explanation

To check the divisibility rule of 657 for 13140:  


1) Multiply the last digit by 3, 0 × 3 = 0.  


2) Add the result to the remaining digits excluding the last digit, 1314 + 0 = 1314.  


3) Check if 1314 is a multiple of 657. While 1314 is a multiple of 657, the additional zero at the end means 13140 is not divisible by 657 without remaining factors.
