Divisibility Rule of 550
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 550.
What is the Divisibility Rule of 550?
The divisibility rule for 550 is a method by which we can find out if a number is divisible by 550 or not without using the division method. Check whether 1100 is divisible by 550 with the divisibility rule.
Step 1: Check if the number is divisible by both 2, 5, and 11 because 550 is the product of these prime factors (550 = 2 × 5 × 11).
Divisibility by 2: The number 1100 ends with a 0, which is even, so it is divisible by 2.
Divisibility by 5: The number 1100 ends with a 0, which is divisible by 5.
Divisibility by 11: The difference between the sum of the digits in odd positions (1+0=1) and the sum of the digits in even positions (1+0=1) is 0, which is divisible by 11.
Step 2: Since 1100 meets all these conditions, it is divisible by 550.
Tips and Tricks for Divisibility Rule of 550
Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 550.
- Understand the prime factors of 550: Memorize the prime factors of 550 (2, 5, and 11) to quickly check divisibility. A number is divisible by 550 if it is divisible by all these prime factors.
- Check each factor individually: For a number to be divisible by 550, it should pass the divisibility tests of 2, 5, and 11.
- Repeat the process for large numbers: Students should keep repeating the divisibility process for each factor until they reach a conclusion.
- 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 550
The divisibility rule of 550 helps us quickly check if a given number is divisible by 550, but common mistakes like calculation errors can lead to incorrect calculations. 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, multiplying the remaining part by a constant, and then adding the result to the last three digits.
Mistake 2
Including all digits in multiplication.
Students should keep in mind that they should multiply only the remaining part of the number, not the last three digits.
Mistake 3
Not repeating the process when the result is large.
Students often stop the process after getting a large number. The process should be repeated until we get the smallest number that is divisible by 571.
Mistake 4
Not considering the positive values.
Students should consider negative results as positive for checking divisibility.
Mistake 5
Confusing the steps
Students often confuse the steps or forget them. To avoid errors, students should practice regularly.
