Tips and Tricks for Divisibility Rule of 880

Learn the divisibility rule to help master division. Let’s learn a few tips and tricks for the divisibility rule of 880.

 

Know the multiples of 880:


Memorize the multiples of 880 (880, 1760, 2640, 3520, etc.) to quickly check divisibility. If the result of the calculation is a multiple of 880, then the number is divisible by 880.

 

Understand the divisibility rules for 8 and 11:


Since 880 is 8×110, a number divisible by 880 must be divisible by both 8 and 11. A number is divisible by 8 if its last three digits form a number divisible by 8. A number is divisible by 11 if the difference between the sum of its digits in odd positions and the sum of its digits in even positions is a multiple of 11.

 

Check using smaller divisors:


For large numbers, check divisibility by 8 and 11 separately. For example, to check if 7040 is divisible by 880, first check divisibility by 8 and 11. Since 040 (40) is divisible by 8 and the alternating sum for 7040 is (7+0)-(0+4)=3, which is not a multiple of 11, 7040 is not divisible by 880.

 

Use the division method to verify:


You can use the division method to verify and cross-check your results, helping to confirm and learn the divisibility rule.

Problem 1

Is 3520 divisible by 880?

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

No, 3520 is not divisible by 880. 

Explanation

To check if 3520 is divisible by 880, we need to ensure it meets the divisibility rules for 8, 11, and 10 (since 880 = 8 × 11 × 10).
 
1) Divisibility by 8: The last three digits are 520, which is not divisible by 8.  

2) Divisibility by 11: The difference between the sum of digits in odd positions (3 + 2) and even positions (5 + 0) is 0, which is divisible by 11.  

3) Divisibility by 10: The last digit is 0, so it's divisible by 10.  
Since 520 is not divisible by 8, 3520 is not divisible by 880.

Problem 2

Check if 8800 is divisible by 880.

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

Yes, 8800 is divisible by 880.

Explanation

To verify the divisibility of 8800 by 880, we check divisibility by 8, 11, and 10:  

1) Divisibility by 8: The last three digits are 800, which is divisible by 8 (800 ÷ 8 = 100).  

2) Divisibility by 11: The difference between the sum of digits in odd positions (8 + 0) and even positions (8 + 0) is 0, which is divisible by 11.  

3) Divisibility by 10: The last digit is 0, so it's divisible by 10.  

All conditions are satisfied, so 8800 is divisible by 880.

Problem 3

Is -1760 divisible by 880?

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

Yes, -1760 is divisible by 880. 

Explanation

We check the divisibility of 1760 (ignoring the negative sign) by 880:
 
1) Divisibility by 8: The last three digits are 760, which is divisible by 8 (760 ÷ 8 = 95).  

2) Divisibility by 11: The difference between the sum of digits in odd positions (1 + 6) and even positions (7 + 0) is 0, which is divisible by 11.  

3) Divisibility by 10: The last digit is 0, so it's divisible by 10.  

Since all conditions are met, -1760 is divisible by 880.

Problem 4

Can 440 be divisible by 880 following the divisibility rule?

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

No, 440 is not divisible by 880. 

Explanation

To check if 440 is divisible by 880, we need to verify its divisibility by 8, 11, and 10:  

1) Divisibility by 8: The last three digits are 440, which is not divisible by 8.  

2) Divisibility by 11: The difference between the sum of digits in odd positions (4 + 0) and even positions (4) is 0, which is divisible by 11.
 
3) Divisibility by 10: The last digit is 0, so it's divisible by 10.  

Since 440 is not divisible by 8, it is not divisible by 880.

Problem 5

Check the divisibility rule of 880 for 9680.

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

Yes, 9680 is divisible by 880.

Explanation

For divisibility of 9680 by 880, we verify divisibility by 8, 11, and 10:  

1) Divisibility by 8: The last three digits are 680, which is divisible by 8 (680 ÷ 8 = 85).  

2) Divisibility by 11: The difference between the sum of digits in odd positions (9 + 8) and even positions (6 + 0) is 11, which is divisible by 11.  

3) Divisibility by 10: The last digit is 0, so it's divisible by 10.  

All conditions are satisfied, so 9680 is divisible by 880.
