Divisibility Rule of 843
The divisibility rule is a way to determine whether a number is divisible by another number without directly performing division. In real life, we can use divisibility rules for quick calculations, dividing things evenly, and sorting items. In this topic, we will learn about the divisibility rule of 843.
What is the Divisibility Rule of 843?
The divisibility rule for 843 is a method by which we can find out if a number is divisible by 843 without using the division method. Check whether 1686 is divisible by 843 using the divisibility rule.
Step 1: Check if the number is divisible by 3, 281, and 1, all factors of 843.
Step 2: For divisibility by 3, sum the digits of the number. If the sum is divisible by 3, then the number is also divisible by 3. For 1686, the digits are 1, 6, 8, and 6. Added together, 1+6+8+6=21, which is divisible by 3.
Step 3: For divisibility by 281, the number must follow the divisibility rule of 281. This involves specific checks or using the division method.
If a number passes both divisibility checks for 3 and 281, it is divisible by 843. If not, it isn't divisible by 843.
Tips and Tricks for Divisibility Rule of 843
Learning the divisibility rule can help students master division. Let’s learn a few tips and tricks for the divisibility rule of 843.
1. Know the factors:
Understand that 843 is a product of 3 and 281. A number divisible by 843 must be divisible by both of these factors.
2. Memorize smaller rules:
It is easier to first apply divisibility rules for smaller numbers like 3. Learn and apply these rules first to quickly assess divisibility.
3. Repeat the process for large numbers:
For large numbers, repeat the divisibility checks for both 3 and 281 to ensure accuracy.
4. 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.
