Divisibility Rule of 769
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 769.
What is the Divisibility Rule of 769?
The divisibility rule for 769 is a method by which we can find out if a number is divisible by 769 or not without using the division method. Let's check whether 1538 is divisible by 769 with the divisibility rule.
Step 1: Multiply the last digit of the number by 2. In 1538, 8 is the last digit, so multiply it by 2. 8 × 2 = 16.
Step 2: Subtract the result from Step 1 from the remaining digits, excluding the last digit. i.e., 153–16 = 137.
Step 3: As it is shown that 137 is not a multiple of 769, the number 1538 is not divisible by 769. If the result from step 2 is a multiple of 769, then the number is divisible by 769.
Tips and Tricks for Divisibility Rule of 769
Learning the divisibility rule will help students master division. Let’s learn a few tips and tricks for the divisibility rule of 769.
- Know the multiples of 769:
Memorize the multiples of 769 (769, 1538, 2307, etc.) to quickly check divisibility. If the result from the subtraction is a multiple of 769, then the number is divisible by 769.
- Use negative numbers:
If the result we get after 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 769.
For example, check if 3076 is divisible by 769 using the divisibility test. Multiply the last digit by 2, i.e., 6 × 2 = 12.
Subtract the remaining digits excluding the last digit by 12, 307–12 = 295. Still, 295 is a large number, hence we will repeat the process again.
Multiply the last digit by 2, 5 × 2 = 10. Now subtract 10 from the remaining numbers excluding the last digit, 29–10 = 19. Since 19 is not a multiple of 769, 3076 is not divisible by 769.
- 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 769
The divisibility rule of 769 helps us to quickly check if the given number is divisible by 769, 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 following the correct steps.
Students should follow the correct steps: multiply the last digit by 2, then subtract the result from the remaining digits excluding the last digit, and check whether it is a multiple of 769.
Mistake 2
Including the last digit in subtraction.
Students should keep in mind to 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 obtaining a large number after subtraction. The process should be repeated until they get the smallest number that is divisible by 769.
Mistake 4
Not considering negative values.
Students may ignore negative values, thinking divisibility rules don't apply to them. The divisibility rule is applicable to negative values too, so students should consider negative values as positive while checking for divisibility.
Mistake 5
Confusing the steps.
Students often confuse or forget the steps. To avoid errors, students should practice regularly.
Divisibility Rule of 769 Examples
Problem 1
Is 2307 divisible by 769?
Yes, 2307 is divisible by 769.
Explanation
To check if 2307 is divisible by 769, we can use the divisibility rule for 769.
1) Consider the last three digits of the number, which are 307.
2) Subtract 307 from the number, 2307 - 307 = 2000.
3) Check if 2000 is divisible by 769. Yes, 2000 is divisible by 769 (769 x 2 = 1538 and 1538 + 462 = 2000).
Problem 2
Check the divisibility rule of 769 for 1538.
Yes, 1538 is divisible by 769.
Explanation
For checking the divisibility of 769 for 1538:
1) Consider the last three digits, which are 538.
2) Subtract 538 from 1538, 1538 - 538 = 1000.
3) Check if 1000 is divisible by 769. Yes, 1000 is not exactly divisible by 769, but if we add 769 to 538, it becomes 1538, meaning 1538 is divisible by 769.
Problem 3
Is -3076 divisible by 769?
Yes, -3076 is divisible by 769.
Explanation
To determine if -3076 is divisible by 769, ignore the negative sign and proceed:
1) Consider the last three digits, which are 076 (or 76).
2) Subtract 76 from 3076, 3076 - 76 = 3000.
3) Check if 3000 is divisible by 769. Yes, 3000 is divisible by 769 (769 x 3 = 2307 and 2307 + 769 = 3076).
Problem 4
Can 1540 be divisible by 769 following the divisibility rule?
No, 1540 isn't divisible by 769.
Explanation
To check if 1540 is divisible by 769:
1) Consider the last three digits, which are 540.
2) Subtract 540 from 1540, 1540 - 540 = 1000.
