Divisibility Rule of 728
The divisibility rule is a way to determine whether a number is divisible by another number without performing actual division. In real life, we can use the divisibility rule for quick calculations, dividing things evenly, and sorting items. In this topic, we will learn about the divisibility rule of 728.
What is the Divisibility Rule of 728?
The divisibility rule for 728 is a method by which we can determine if a number is divisible by 728 without performing actual division. To illustrate, let's check whether 1456 is divisible by 728 using this rule.
Step 1: Divide the number into three groups from the right, each consisting of three digits. If a group has less than three digits, pad with zeros. For 1456, the groups are 001 and 456.
Step 2: If each group is divisible by 728, then the whole number is divisible by 728. Here, neither 001 nor 456 is divisible by 728.
Step 3: If either group is not divisible by 728, the number is not divisible by 728.
Tips and Tricks for Divisibility Rule of 728
Learning the divisibility rule can help students master division. Here are a few tips and tricks for the divisibility rule of 728.
Know the multiples of 728:
Memorize the multiples of 728 (728, 1456, 2184, etc.) to quickly check divisibility. If each group formed is a multiple of 728, then the number is divisible by 728.
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 confirm their findings and also learn.
Common Mistakes and How to Avoid Them in Divisibility Rule of 728

Mistake 1
Not following the correct steps.
Students should follow the correct steps by dividing the number into groups of three digits and checking each group's divisibility by 728.
Mistake 2
Including digits outside the defined groups.
Ensure that digits are only considered within their respective groups.
Mistake 3
Not verifying with actual division.
Always verify results using the division method to confirm accuracy.
Mistake 4
Confusing the steps.
Students often confuse the steps or forget them. Practice regularly to avoid this error.
Mistake 5
Overlooking the use of the division method.
Use the division method to verify results and ensure accuracy.
Divisibility Rule of 728 Examples
Problem 1
Is the number of pages in a book, 2912, divisible evenly by 728 to form complete volumes?
Yes, 2912 is divisible by 728.
Explanation
To check if 2912 is divisible by 728, we perform the division. 2912 ÷ 728 = 4. Since the result is an integer, 2912 is divisible by 728, allowing for complete volumes.
Problem 2
A factory produces 1456 gadgets in a batch. Can these be evenly packed into boxes containing 728 gadgets each?
No, 1456 is not divisible by 728.
Explanation
To determine if 1456 is divisible by 728, divide 1456 by 728. 1456 ÷ 728 = 2. Since the result is an integer, it appears divisible, but further checking shows no remainder, confirming it divides evenly.
Problem 3
Is a shipment of 3640 items divisible by 728 for equal distribution among stores?
Yes, 3640 is divisible by 728.
Explanation
To verify if 3640 is divisible by 728, perform the division. 3640 ÷ 728 = 5. Since the result is an integer, 3640 can be evenly distributed among 5 stores.
Problem 4
A company has 2184 boxes of supplies. Can they be divided into equal groups of 728?
No, 2184 is not divisible by 728.
Explanation
To check if 2184 is divisible by 728, divide 2184 by 728. 2184 ÷ 728 ≈ 3. Since there is a remainder, 2184 cannot be evenly divided into groups of 728.
Problem 5
During a festival, organizers have 4368 tickets. Can these be evenly divided among 728 participants?
Yes, 4368 is divisible by 728.
Explanation
To determine if 4368 is divisible by 728, divide 4368 by 728. 4368 ÷ 728 = 6. Since the result is an integer and there is no remainder, the tickets can be evenly divided among the participants.
