Divisibility Rule of 449
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 divisibility rules for quick math, dividing things evenly, and sorting things. In this topic, we will learn about the divisibility rule of 449.
What is the Divisibility Rule of 449?
The divisibility rule for 449 is a method by which we can find out if a number is divisible by 449 or not without using the division method.
Check whether 1347 is divisible by 449 with the divisibility rule.
Step 1: Multiply the last digit of the number by 9. For 1347, 7 is the last digit, so multiply it by 9. 7 × 9 = 63.
Step 2: Subtract the result from Step 1 from the remaining part of the number but do not include the last digit. i.e., 134–63 = 71.
Step 3: As it is shown that 71 is not a multiple of 449, the number is not divisible by 449. If the result from step 2 were a multiple of 449, then the number would be divisible by 449.
Tips and Tricks for Divisibility Rule of 449
Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 449.
- Know the multiples of 449: Memorize the multiples of 449 (449, 898, 1347, 1796…etc.) to quickly check divisibility. If the result from the subtraction is a multiple of 449, then the number is divisible by 449.
- Use the negative numbers: If the result we get after the subtraction is negative, ignore the negative sign and consider it as positive for checking the divisibility of a number.
- Repeat the process for large numbers: Students should keep repeating the divisibility process until they reach a small number that is divisible by 449.
For example: Check if 4041 is divisible by 449 using the divisibility test.
Multiply the last digit by 9, i.e., 1 × 9 = 9. Subtract the remaining digits excluding the last digit by 9, 404–9 = 395.
Since 395 is still large, repeat the process: multiply the last digit by 9, 5 × 9 = 45.
Now subtract 45 from the remaining numbers excluding the last digit, 39–45 = -6.
Since 6 is not a multiple of 449, 4041 is not divisible by 449.
- 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 verify and also learn.
Common Mistakes and How to Avoid Them in Divisibility Rule of 449
The divisibility rule of 449 helps us quickly check if a given number is divisible by 449, but common mistakes like calculation errors can lead to incorrect conclusions. Here we will understand some common mistakes and how to avoid them.
Mistake 1
Not following the correct steps.
Students should follow the correct steps of multiplying the last digit by 9 and then subtracting the result from the remaining digits excluding the last digit to check whether it is a multiple of 449.
Divisibility Rule of 449 Examples
Problem 1
Is the number of pages in a book, 1,347, divisible by 449?
No, 1,347 is not divisible by 449.
Explanation
To check if 1,347 is divisible by 449, we can quickly divide 1,347 by 449. If the quotient is a whole number, then 1,347 is divisible by 449. Upon performing the division, 1,347 ÷ 449 ≈ 3.0, which is not a whole number. Therefore, 1,347 is not divisible by 449.
Problem 2
A museum has 898 visitors over three consecutive days. Can the number of visitors be evenly distributed across the three days, following the divisibility rule of 449?
No, 898 cannot be evenly distributed by 449 into three days.
Explanation
To determine if 898 can be divided evenly by 449, divide 898 by 449. The division gives approximately 2.0, which means 898 is not evenly divisible by 449. Therefore, the number of visitors cannot be evenly distributed into the three days.
Problem 3
A farmer harvested 1,347 apples from his orchard. Can he place them into baskets with each basket holding 449 apples?
Yes, the farmer can place them into baskets with each basket holding 449 apples.
Explanation
To check if 1,347 apples can be placed into baskets of 449 apples each, divide 1,347 by 449. The division results in exactly 3, meaning 1,347 is divisible by 449. Therefore, the apples can be evenly distributed into baskets.
Problem 4
Is the total weight of a shipment, 2,245 kg, divisible by 449?
Yes, 2,245 kg is divisible by 449.
Explanation
To determine if 2,245 is divisible by 449, we perform the division: 2,245 ÷ 449 = 5. The result is a whole number, confirming that 2,245 is divisible by 449.
Problem 5
A library wants to organize their collection of 1,796 books into shelves, each holding 449 books. Is this possible?
No, 1,796 books cannot be evenly placed on shelves of 449 books each.
Explanation
To find out if 1,796 books can be divided into shelves of 449 books, divide 1,796 by 449. The division gives approximately 4.0, indicating that 1,796 is not divisible by 449. Therefore, the books cannot be evenly organized on the shelves.
