Divisibility Rule of 793
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 793.
What is the Divisibility Rule of 793?
The divisibility rule for 793 is a method by which we can find out if a number is divisible by 793 or not without using the division method. Check whether 1586 is divisible by 793 with the divisibility rule.
Step 1: Multiply the last digit of the number by 4, here in 1586, 6 is the last digit multiply it by 4. 6 × 4 = 24
Step 2: Subtract the result from Step 1 from the remaining values but do not include the last digit. i.e., 158–24 = 134.
Step 3: As it is shown that 134 is not a multiple of 793, therefore, the number is not divisible by 793. If the result from step 2 is a multiple of 793, then the number is divisible by 793.
Tips and Tricks for Divisibility Rule of 793
Learning the divisibility rule will help kids to master division. Let’s learn a few tips and tricks for the divisibility rule of 793.
Know the multiples of 793:
Memorize the multiples of 793 (793, 1586, 2379, etc.) to quickly check the divisibility. If the result from the subtraction is a multiple of 793, then the number is divisible by 793.
Use the negative numbers:
If the result we get after the subtraction is negative, we will avoid the symbol and consider it as positive for checking the divisibility of a number.
Repeat the process for large numbers:
Students should keep repeating the divisibility process until they reach a small number that is divisible by 793.
For example: Check if 4758 is divisible by 793 using the divisibility test.
Multiply the last digit by 4, i.e., 8 × 4 = 32.
Subtract the result from the remaining digits excluding the last digit, 475–32 = 443.
Still, 443 is a large number in this context, hence we will repeat the process again: multiply the last digit by 4, 3 × 4 = 12.
Now subtracting 12 from the remaining numbers excluding the last digit, 44–12 = 32.
As 32 is not a multiple of 793, 4758 is not divisible by 793.
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 793
The divisibility rule of 793 helps us to quickly check if the given number is divisible by 793, 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 that are multiplying the last digit with 4 and then subtracting the result from the remaining digits excluding the last digit and checking whether it is a multiple of 793.
Mistake 2
Including the last digit in subtraction
Students should keep in mind that they should exclude the last digit while subtracting and include all the remaining digits.
Mistake 3
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 the smallest number that is divisible by 793.
Mistake 4
Not considering the negative values.
Students consider the negative values thinking divisibility rules don't apply to negative values. 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 the steps. To avoid this error, students should practice regularly.
Divisibility Rule of 793 Examples
Problem 1
Is 1586 divisible by 793?
Yes, 1586 is divisible by 793.
Explanation
To check if 1586 is divisible by 793 using a hypothetical rule:
1) Double the last digit: 6 × 2 = 12.
2) Subtract this from the remaining leading digits: 158 - 12 = 146.
3) Check if 146 is a multiple of 793 or if further steps lead to a remainder of 0. Since 146 divided by 793 gives a remainder of 0, 1586 is divisible by 793.
Problem 2
Check the divisibility of 793 for 3965.
No, 3965 is not divisible by 793.
Explanation
Using a hypothetical rule:
1) Double the last digit: 5 × 2 = 10.
2) Subtract this from the remaining leading digits: 396 - 10 = 386.
3) Since 386 divided by 793 does not result in a remainder of 0, 3965 is not divisible by 793.
Problem 3
Is -2379 divisible by 793?
No, -2379 is not divisible by 793.
Explanation
Ignore the negative sign and apply the hypothetical rule:
1) Double the last digit: 9 × 2 = 18.
2) Subtract this from the remaining leading digits: 237 - 18 = 219.
3) Since 219 divided by 793 does not result in a remainder of 0, -2379 is not divisible by 793.
Problem 4
Can 793 be a divisor of 476?
No, 476 is not divisible by 793.
Explanation
Using a hypothetical rule:
1) Double the last digit: 6 × 2 = 12.
2) Subtract this from the remaining leading digits: 47 - 12 = 35.
3) Since 35 divided by 793 does not result in a remainder of 0, 476 is not divisible by 793.
Problem 5
Check the divisibility rule of 793 for 15860.
Yes, 15860 is divisible by 793.
Explanation
Using a hypothetical rule:
1) Double the last digit: 0 × 2 = 0.
2) Subtract this from the remaining leading digits: 1586 - 0 = 1586.
3) Since 1586 divided by 793 results in a remainder of 0, 15860 is divisible by 793.
