Divisibility Rule of 615
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 615.
What is the Divisibility Rule of 615?
The divisibility rule for 615 is a method by which we can find out if a number is divisible by 615 or not without using the division method. Check whether 1845 is divisible by 615 with the divisibility rule.
Step 1: Check divisibility by 5. The last digit should be 0 or 5. Here in 1845, the last digit is 5, so it is divisible by 5.
Step 2: Check divisibility by 3. Sum all digits: 1+8+4+5=18. Since 18 is divisible by 3, 1845 is also divisible by 3.
Step 3: Check divisibility by 41. Divide 1845 by 41. If the quotient is an integer, then it is divisible by 41.
Tips and Tricks for Divisibility Rule of 615
Learning the divisibility rule will help kids to master division. Let’s learn a few tips and tricks for the divisibility rule of 615.
- Know the multiples of 615: Memorize the multiples of 615 to quickly check divisibility. If the number is found in the multiples list, it is divisible by 615.
- 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.
Common Mistakes and How to Avoid Them in Divisibility Rule of 615
The divisibility rule of 615 helps us to quickly check if the given number is divisible by 615, but common mistakes like calculation errors can lead to incorrect results. Here we will understand some common mistakes to avoid.
Mistake 1
Not checking all factors.
Ensure that the number is divisible by each factor of 615 (5, 3, and 41) to confirm divisibility.
Mistake 2
Incorrect summation for divisibility by 3.
Accurately sum all digits and check divisibility by 3.
Mistake 3
Skipping verification.
Always verify by using the division method to ensure accuracy.
Mistake 4
Miscalculating sums or products.
Double-check calculations when summing digits or performing multiplications.
Mistake 5
Confusing the steps.
Practice regularly to remember and correctly apply the steps.
Divisibility Rule of 615 Examples
Problem 1
Can 3690 be divisible by 615?
Yes, 3690 is divisible by 615.
Explanation
To determine if 3690 is divisible by 615, we need to check if it meets the divisibility conditions for each factor of 615: 3, 5, and 41.
1) Check divisibility by 3: The sum of the digits is 3 + 6 + 9 + 0 = 18, which is divisible by 3.
2) Check divisibility by 5: The last digit is 0, which is divisible by 5.
3) Check divisibility by 41: Divide 3690 by 41, resulting in 90, which is a whole number.
Since 3690 meets all conditions, it is divisible by 615.
Problem 2
Is 492 divisible by 615?
No, 492 is not divisible by 615.
Explanation
To check if 492 is divisible by 615, we must verify divisibility by 3, 5, and 41.
1) Check divisibility by 3: The sum of the digits is 4 + 9 + 2 = 15, which is divisible by 3.
2) Check divisibility by 5: The last digit is 2, which is not divisible by 5.
3) Since 492 is not divisible by 5, it is not divisible by 615.
Problem 3
Verify if 1230 is divisible by 615.
Yes, 1230 is divisible by 615.
Explanation
To determine if 1230 is divisible by 615, we must check divisibility by 3, 5, and 41.
1) Check divisibility by 3: The sum of the digits is 1 + 2 + 3 + 0 = 6, which is divisible by 3.
2) Check divisibility by 5: The last digit is 0, which is divisible by 5.
3) Check divisibility by 41: Divide 1230 by 41, resulting in 30, which is a whole number.
Since 1230 satisfies all conditions, it is divisible by 615.
Problem 4
Is 1845 divisible by 615?
No, 1845 is not divisible by 615.
Explanation
To check if 1845 is divisible by 615, we must verify divisibility by 3, 5, and 41.
1) Check divisibility by 3: The sum of the digits is 1 + 8 + 4 + 5 = 18, which is divisible by 3.
2) Check divisibility by 5: The last digit is 5, which is divisible by 5.
3) Check divisibility by 41: Divide 1845 by 41, resulting in approximately 45, which is not a whole number.
Since 1845 does not meet the divisibility condition for 41, it is not divisible by 615.
Problem 5
Verify if 7380 is divisible by 615.
Yes, 7380 is divisible by 615.
Explanation
To determine if 7380 is divisible by 615, we must check divisibility by 3, 5, and 41.
1) Check divisibility by 3: The sum of the digits is 7 + 3 + 8 + 0 = 18, which is divisible by 3.
2) Check divisibility by 5: The last digit is 0, which is divisible by 5.
3) Check divisibility by 41: Divide 7380 by 41, resulting in 180, which is a whole number.
Since 7380 satisfies all conditions, it is divisible by 615.
