Divisibility Rule of 515
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 515.
What is the Divisibility Rule of 515?
The divisibility rule for 515 is a method by which we can find out if a number is divisible by 515 or not without using the division method. Check whether 1030 is divisible by 515 with the divisibility rule.
Step 1: Check if the number is divisible by both 5 and 103, since 515 = 5 × 103.
Step 2: A number is divisible by 5 if its last digit is 0 or 5. In 1030, the last digit is 0, so it is divisible by 5.
Step 3: To check divisibility by 103, you may need to use the division method directly or verify using a known multiple. For simplicity, check if 1030 divided by 103 gives an integer.
Step 4: Since both conditions are met (divisible by 5 and 103), 1030 is divisible by 515.
Tips and Tricks for Divisibility Rule of 515
Learn divisibility rules to help master division. Let’s learn a few tips and tricks for the divisibility rule of 515.
Know the multiples of 515: Memorize the multiples of 515 (515, 1030, 1545, etc.) to quickly check divisibility.
Break down into smaller divisibility checks: Since 515 = 5 × 103, first check divisibility by 5 and then by 103.
Use typical division for large numbers: For larger numbers, it might be easier to use division to check divisibility by 103.
Use the division method to verify: Always verify and cross-check your results with actual division to ensure accuracy.
Common Mistakes and How to Avoid Them in Divisibility Rule of 515
The divisibility rule of 515 helps us quickly check if a given number is divisible by 515, but common mistakes like calculation errors can lead to incorrect conclusions. Here, we will understand some common mistakes and how to avoid them.
Mistake 1
Not checking for both factors (5 and 103).
Always ensure the number is divisible by both 5 and 103.
Mistake 2
Misidentifying the last digit for divisibility by 5.
Remember, a number is divisible by 5 if it ends in 0 or 5.
Mistake 3
Not verifying with division for large numbers.
Use division as a verification step, especially for divisibility by 103.
Mistake 4
Ignoring order of steps.
Follow the correct sequence of divisibility checks: first by 5, then by 103.
Mistake 5
Confusing the steps.
Practice regularly and memorize the correct steps for clarity.
Divisibility Rule of 515 Examples
Problem 1
Is 1545 divisible by 515?
Yes, 1545 is divisible by 515.
Explanation
To check if 1545 is divisible by 515, consider the context of a new divisibility rule:
1) Multiply the last digit of the number by 3, 5 × 3 = 15.
2) Subtract the result from the remaining digits excluding the last digit, 154 – 15 = 139.
3) Multiply the result by 2, 139 × 2 = 278.
4) Check if 278 is a multiple of 515. No, it's not; however, as we applied the wrong rule, reevaluate directly: 1545 ÷ 515 = 3.
Problem 2
Check the divisibility rule of 515 for 3090.
No, 3090 is not divisible by 515.
Explanation
Using a new approach to check the divisibility of 3090 by 515:
1) Double the last two digits of the number, 90 × 2 = 180.
2) Subtract the result from the remaining digits excluding the last two digits, 30 – 180 = -150.
3) Check if the result is a multiple of 515. No, -150 is not a multiple of 515.
Problem 3
Is 515 divisible by 515?
Yes, 515 is divisible by 515.
Explanation
Since a number is always divisible by itself:
1) Directly check: 515 ÷ 515 = 1.
2) No further steps are needed as the result is clearly an integer.
Problem 4
Can 2060 be divisible by 515 following the divisibility rule?
Yes, 2060 is divisible by 515.
Explanation
To check if 2060 is divisible by 515:
1) Multiply the last two digits by 4, 60 × 4 = 240.
2) Subtract this from the remaining digits, 20 – 240 = -220.
3) Add the result to twice the original number, -220 + (2 × 2060) = 3900.
4) Divide 3900 by 515 to find it equals 7.57, which indicates a misapplication of an assumed rule. Correctly, check: 2060 ÷ 515 = 4.
Problem 5
Check the divisibility rule of 515 for 7725.
No, 7725 is not divisible by 515.
Explanation
To test the divisibility of 7725 by 515:
1) Triple the last two digits, 25 × 3 = 75.
2) Subtract this from the remaining digits, 77 – 75 = 2.
3) Check if 2 is a multiple of 515. No, it is not.
4) Direct check: 7725 ÷ 515 = 15.0097, which is not an integer.
