Divisibility Rule of 786
The divisibility rule is a way to determine 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 items. In this topic, we will learn about the divisibility rule of 786.
What is the Divisibility Rule of 786?
The divisibility rule for 786 is a method by which we can find out if a number is divisible by 786 or not without using the division method. Check whether 4716 is divisible by 786 with the divisibility rule.
Step 1: Break down 786 into its prime factors, which are 2, 3, and 131. Check if 4716 is divisible by each of these factors.
- For divisibility by 2: The number 4716 ends in 6, which is even, hence divisible by 2.
- For divisibility by 3: Add up the digits of 4716 (4+7+1+6=18). Since 18 is divisible by 3, 4716 is divisible by 3.
- For divisibility by 131: This step requires direct division or confirmation using a calculator, as there isn't a simple rule like for 2 or 3.
Step 2: Since 4716 is divisible by 2 and 3, check the divisibility by 131. If 4716 is divisible by 131, then it is divisible by 786.
Tips and Tricks for Divisibility Rule of 786
Learn divisibility rules to help master division. Let’s learn a few tips and tricks for the divisibility rule of 786.
Know the multiples of 786:
Memorize the multiples of 786 (786, 1572, 2358, etc.) to quickly check divisibility. If the result of breaking down the number is a multiple of 786, then the number is divisible by 786.
Use prime factorization:
Understanding the prime factors (2, 3, 131) of 786 can aid in determining divisibility by checking these simpler divisibility rules first.
Repeat the process for large numbers:
Students should keep repeating the divisibility process until they confidently determine divisibility by 786. This includes checking each prime factor.
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 786
The divisibility rule of 786 helps us to quickly check if a given number is divisible by 786, but common mistakes like calculation errors can lead to incorrect results. Here we will understand some common mistakes and how to avoid them.
Mistake 1
Not following the correct steps.
Students should follow the correct steps, which include checking divisibility by each prime factor of 786 (2, 3, and 131).
Divisibility Rule of 786 Examples
Problem 1
Is 4716 divisible by 786?
No, 4716 is not divisible by 786.
Explanation
To check if 4716 is divisible by 786, let's use a hypothetical divisibility rule for 786.
1) Sum the digits of the number, 4 + 7 + 1 + 6 = 18.
2) Check if the sum is divisible by 18 (a factor of 786). 18 ÷ 18 = 1.
3) Since the sum is divisible by 18, proceed to divide 4716 by 786. 4716 ÷ 786 ≈ 6. This is not an integer, so 4716 is not divisible by 786.
Problem 2
Check the divisibility rule of 786 for 1572.
Yes, 1572 is divisible by 786.
Explanation
Using a hypothetical divisibility rule for 786:
1) Group the digits in sets of three from right to left, getting 1, 572.
2) Multiply the sum of each group by its position (1-based from the right), (1 × 1) + (572 × 2) = 1145.
3) Since 1145 is not divisible by 786, check the direct division: 1572 ÷ 786 = 2. This is an integer, so 1572 is divisible by 786.
Problem 3
Is -1572 divisible by 786?
Yes, -1572 is divisible by 786.
Explanation
To verify if -1572 is divisible by 786:
1) Ignore the negative sign and apply the hypothetical rule.
2) Group the digits in sets of three from right to left, getting 1, 572.
3) Multiply the sum of each group by its position (1-based from the right), (1 × 1) + (572 × 2) = 1145.
4) Since 1145 is not divisible by 786, check the direct division: -1572 ÷ 786 = -2. This is an integer, so -1572 is divisible by 786.
Problem 4
Can 2358 be divisible by 786 following the divisibility rule?
No, 2358 is not divisible by 786.
Explanation
To check if 2358 is divisible by 786:
1) Group the digits in sets of three from right to left, getting 2, 358.
2) Multiply the sum of each group by its position (1-based from the right), (2 × 1) + (358 × 2) = 718.
3) Since 718 is not divisible by 786, check the direct division: 2358 ÷ 786 ≈ 3. This is not an integer, so 2358 is not divisible by 786.
Problem 5
Check the divisibility rule of 786 for 7860.
Yes, 7860 is divisible by 786.
Explanation
To verify the divisibility of 7860 by 786:
1) Group the digits in sets of three from right to left, getting 7, 860.
2) Multiply the sum of each group by its position (1-based from the right), (7 × 1) + (860 × 2) = 1727.
3) Since 1727 is not divisible by 786, check the direct division: 7860 ÷ 786 = 10. This is an integer, so 7860 is divisible by 786.
