Divisibility Rule of 871
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 things. In this topic, we will learn about the divisibility rule of 871.
What is the Divisibility Rule of 871?
The divisibility rule for 871 is a method by which we can find out if a number is divisible by 871 or not without using the division method. Check whether 2613 is divisible by 871 with the divisibility rule.
Step 1: Check if the number can be split into smaller groups that add up to multiples of 871. For example, 2613 can be split into 1742 and 871.
Step 2: Verify if each group is a multiple of 871. In this case, since 1742 + 871 = 2613 and 871 is a known multiple, 2613 is divisible by 871.
Tips and Tricks for Divisibility Rule of 871
Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 871.
Know the multiples of 871:
Memorize the multiples of 871 (871, 1742, 2613, etc.) to quickly check divisibility. If the result from adding or splitting is a multiple of 871, then the number is divisible by 871.
Use subtraction for verification:
If the number is close to a known multiple of 871, subtract it to see if the remainder is zero, confirming divisibility.
Repeat the process for large numbers:
For larger numbers, students should keep repeating the divisibility process using known multiples of 871 to verify divisibility.
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 871
The divisibility rule of 871 helps us quickly check if a given number is divisible by 871, but common mistakes like calculation errors lead to incorrect conclusions. Here we will understand some common mistakes that will help you avoid them.
Mistake 1
Not identifying correct multiples.
Ensure you correctly identify known multiples of 871 to use them in the divisibility check.
Divisibility Rule of 871 Examples
Problem 1
Is 2613 divisible by 871?
Yes, 2613 is divisible by 871.
Explanation
To determine if 2613 is divisible by 871, we can apply a hypothetical divisibility rule for 871.
1) Assume the rule requires multiplying the last two digits of the number by a specific factor, say 3, 13 × 3 = 39.
2) Subtract the result from the remaining leading digits, 26 - 39 = -13.
3) Since -13 is not a multiple of 871, it seems the assumed rule might not directly work. Thus, a division confirms: 2613 ÷ 871 = 3 with no remainder.
Problem 2
Check the divisibility rule of 871 for 8710.
Yes, 8710 is divisible by 871.
Explanation
We explore a rule for 871 using a different method:
1) Consider multiplying the last digit by a factor, for instance, 7, 0 × 7 = 0.
2) Subtract this from the remaining digits of the number, 871 - 0 = 871.
3) Since 871 is clearly a multiple of 871, 8710 is divisible by 871.
Problem 3
Is -1742 divisible by 871?
Yes, -1742 is divisible by 871.
Explanation
To check if -1742 is divisible by 871, we disregard the negative sign for calculation.
1) Assume a rule involving the last digit, multiply it by 4, 2 × 4 = 8.
2) Subtract the result from the remaining portion of the number, 174 - 8 = 166.
3) Notice that directly dividing gives -1742 ÷ 871 = -2, confirming divisibility.
Problem 4
Can 4355 be divisible by 871 following a divisibility rule?
No, 4355 isn't divisible by 871.
Explanation
Let's test a divisibility approach:
1) Assume multiplying the last digit by 5, 5 × 5 = 25.
2) Subtract this from the remaining number, 435 - 25 = 410.
3) Since 410 is not a multiple of 871, 4355 is not divisible by 871.
Problem 5
Check the divisibility rule of 871 for 1742.
Yes, 1742 is divisible by 871.
Explanation
Following a hypothetical rule:
1) Multiply the last digit by 6, 2 × 6 = 12.
2) Subtract this from the rest of the digits, 174 - 12 = 162.
3) Although this doesn't directly confirm divisibility, dividing 1742 by 871 yields 2, confirming divisibility.
