Divisibility Rule of 799
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 799.
What is the Divisibility Rule of 799?
The divisibility rule for 799 is a method by which we can find out if a number is divisible by 799 or not without using the division method. Check whether 2397 is divisible by 799 with the divisibility rule.
Step 1: Divide the number into blocks of three digits from the right. Here, 2397 becomes 2,397.
Step 2: Multiply the leftmost block by 2 and subtract it from the next block to the right. For 2397, multiply 2 by 2, and subtract it from 397: 397 - (2×2) = 393.
Step 3: If the result from Step 2 is a multiple of 799 or reduces to zero, the number is divisible by 799. In this case, 393 is not a multiple of 799, so 2397 is not divisible by 799.
Tips and Tricks for Divisibility Rule of 799
Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 799.
Know the multiples of 799:
Memorize the multiples of 799 (799, 1598, 2397, etc.) to quickly check the divisibility. If the result from the subtraction is a multiple of 799, the number is divisible by 799.
Use the division method to verify:
Students can use the division method as a way to verify and crosscheck their results. This will help them to verify and also learn.
Repeat the process for large numbers:
Students should keep repeating the divisibility process until they reach a small number that is divisible by 799.
For example: Check if 4794 is divisible by 799 using the divisibility test.
Divide into blocks: 4794 becomes 4,794.
Multiply the left block by 2: 4 × 2 = 8.
Subtract from the next block: 794 - 8 = 786.
Since 786 is not a multiple of 799, repeat the process if needed.
Common Mistakes and How to Avoid Them in Divisibility Rule of 799
The divisibility rule of 799 helps us to quickly check if the given number is divisible by 799, but common mistakes like calculation errors lead to incorrect calculations. Here we will understand some common mistakes that will help you to understand.
Mistake 1
Not following the correct steps.
Students should follow the correct steps of multiplying and subtracting according to the rules and checking whether the result is a multiple of 799.
Mistake 2
Not repeating the process when the result is large.
Students often stop the process after they have got a large number as a result after subtraction. The process should be repeated until we get a small number that is divisible by 799.
Mistake 3
Confusing the steps.
Students often confuse the steps or forget them; to avoid this, students should practice regularly.
Mistake 4
Not considering the negative values.
Students might ignore negative values thinking divisibility rules don't apply to negative numbers. But the divisibility rule is applicable for negative values too. So students should consider the negative values as positive while checking for divisibility.
Mistake 5
Confusing the steps.
Students often confuse the steps or forget them. To avoid this error, students should practice regularly.
Divisibility Rule of 799 Examples
Problem 1
Is the library's special collection of 2397 rare books divisible by 799?
Yes, 2397 is divisible by 799.
Explanation
To check if 2397 is divisible by 799, we can use the rule:
1) Multiply the last two digits by 8, 97 × 8 = 776.
2) Subtract this result from the remaining digits, excluding the last two digits, 23 - 776 = -753.
3) Since -753 is a multiple of 799, the original number is divisible by 799.
Problem 2
Can the museum's exhibit of 1598 artifacts be organized into groups of 799?
Yes, 1598 is divisible by 799.
Explanation
To check divisibility by 799:
1) Multiply the last two digits by 8, 98 × 8 = 784.
2) Subtract this from the rest of the number, excluding the last two digits, 15 - 784 = -769.
3) Since -769 is a multiple of 799, the number 1598 is divisible by 799.
Problem 3
Is the batch of 3196 custom-made toys divisible by 799?
No, 3196 is not divisible by 799.
Explanation
To verify using the divisibility rule:
1) Multiply the last two digits by 8, 96 × 8 = 768.
2) Subtract from the remaining digits, excluding the last two, 31 - 768 = -737.
3) Since -737 is not a multiple of 799, 3196 is not divisible by 799.
Problem 4
Is a shipment of 4794 electronic gadgets divisible by 799?
Yes, 4794 is divisible by 799.
Explanation
To apply the divisibility rule:
1) Multiply the last two digits by 8, 94 × 8 = 752.
2) Subtract the result from the remaining digits, 47 - 752 = -705.
3) Since -705 is a multiple of 799, 4794 is divisible by 799.
Problem 5
Can a total of 5593 artwork pieces be divided equally among 799 galleries?
No, 5593 is not divisible by 799.
Explanation
Following the divisibility rule:
1) Multiply the last two digits by 8, 93 × 8 = 744.
2) Subtract from the rest of the number, 55 - 744 = -689.
3) Since -689 is not a multiple of 799, 5593 is not divisible by 799.
