Divisibility Rule of 841
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 841.
What is the Divisibility Rule of 841?
The divisibility rule for 841 is a method by which we can find out if a number is divisible by 841 or not without using the division method. Check whether 1682 is divisible by 841 with the divisibility rule.
Step 1: Divide the number into two parts. For 1682, consider the first part as 1 and the second part as 682.
Step 2: Check if the first part, 1, is a multiple of 841. Since it is not, multiply the first part by 10 and add it to the second part: 10×1+682=692.
Step 3: As 692 is not a multiple of 841, repeat the process. Multiply the first part by 10 again and add it to the second part: 10×6+92=152.
Step 4: 152 is a multiple of 841, which means the original number 1682 is divisible by 841.
Tips and Tricks for Divisibility Rule of 841
Learn divisibility rules to help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 841.
1. Know the multiples of 841:
Memorize the multiples of 841 to quickly check divisibility. If the result from the addition is a multiple of 841, then the number is divisible by 841.
2. Use the negative numbers:
If the result we get after the process is negative, we will avoid the symbol and consider it as positive for checking divisibility.
3. Repeat the process for large numbers:
Students should keep repeating the divisibility process until they reach a small number that is divisible by 841. For example: Check if 4205 is divisible by 841 using the divisibility test.
Step 1: Divide into parts: 4 and 205.
Step 2: Multiply the first part by 10 and add to the second: 10×4+205=245.
Step 3: 245 is a multiple of 841, so 4205 is divisible by 841.
4. 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.
Common Mistakes and How to Avoid Them in Divisibility Rule of 841
The divisibility rule of 841 helps us to quickly check if the given number is divisible by 841, but common mistakes like calculation errors lead to incorrect results. 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, dividing the number into parts, multiplying and adding to check if it is a multiple of 841.
Mistake 2
Incorrectly dividing the number into parts.
Students should carefully divide the number into the correct parts as described in the steps.
Mistake 3
Not repeating the process when needed.
Students often stop the process too soon. The process should be repeated until a multiple of 841 is found.
Mistake 4
Not considering negative values.
Students should consider negative results as positive for checking divisibility.
Mistake 5
Confusing the steps.
Students often confuse the steps or forget the steps; regular practice can help avoid this error.
