Divisibility Rule of 685
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 685.
What is the Divisibility Rule of 685?
The divisibility rule for 685 is a method by which we can find out if a number is divisible by 685 or not without using the division method. Check whether 1370 is divisible by 685 with the divisibility rule.
Step 1: Divide the number into two parts: the last three digits and the remaining digits. Here, 370 is the last three digits and 1 is the remaining value.
Step 2: Check if the number formed by the last three digits (370) is divisible by 685. If not, the entire number is not divisible by 685.
Step 3: Since 370 is not divisible by 685, 1370 is not divisible by 685.
Tips and Tricks for Divisibility Rule of 685
Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 685.
- Know the multiples of 685: Memorize the multiples of 685 (685, 1370, 2055, etc.) to quickly check divisibility. If the last three digits form a multiple of 685, then the number is divisible by 685.
- Repeat the process for large numbers: Students should keep applying the divisibility process for each segment of large numbers until they reach a segment that is divisible by 685.
- 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 685
The divisibility rule of 685 helps us to quickly check if the given number is divisible by 685, but common mistakes like calculation errors lead to incorrect conclusions. Here we will understand some common mistakes that will help you to avoid errors.
Mistake 1
Not checking the last three digits.
Students should ensure they analyze the last three digits to see if they form a multiple of 685.
Mistake 2
Including digits outside the last three for divisibility check.
Only consider the last three digits for checking divisibility by 685.
Mistake 3
Not repeating the process when dealing with large numbers.
For larger numbers, check each segment of three digits until a divisible segment is confirmed.
Mistake 4
Confusing the process with other divisibility rules.
Ensure understanding of the specific steps for 685, focusing on the last three digits only.
Mistake 5
Confusing the steps.
Practice regularly to remember the steps clearly.
