Divisibility Rule of 838
The divisibility rule is a method to determine whether a number is divisible by another number without using traditional division. In real life, we can use divisibility rules for quick calculations, dividing things evenly, and organizing items. In this topic, we will learn about the divisibility rule of 838.
What is the Divisibility Rule of 838?
The divisibility rule for 838 is a method that allows us to determine if a number is divisible by 838 without using division. Let's check whether 2514 is divisible by 838 using the divisibility rule.
Step 1: Multiply the last three digits of the number by 2. Here, in 2514, the last three digits are 514. Multiply it by 2: 514 × 2 = 1028.
Step 2: Subtract the result from Step 1 from the remaining part of the number, excluding the last three digits. So, subtract 1028 from 2 (since 2 is the remaining part of the number): 2 - 1028 = -1026.
Step 3: If the result is a multiple of 838 or zero, then the number is divisible by 838. Since -1026 is not a multiple of 838, 2514 is not divisible by 838.
Tips and Tricks for Divisibility Rule of 838
Learning the divisibility rule can help students master division. Let’s learn a few tips and tricks for the divisibility rule of 838.
Know the multiples of 838:
Memorize the multiples of 838 (838, 1676, 2514, etc.) to quickly check divisibility. If the result from the subtraction is a multiple of 838, then the number is divisible by 838.
Use absolute values:
If the result after subtraction is negative, consider its absolute value for checking divisibility.
Repeat the process for large numbers:
Students should repeat the divisibility process until they reach a smaller number that can easily be checked for divisibility by 838.
Use the division method to verify:
Students can use the division method to verify and cross-check their results, ensuring accuracy.
Common Mistakes and How to Avoid Them in Divisibility Rule of 838
The divisibility rule of 838 helps us quickly determine if a number is divisible by 838, but common mistakes like calculation errors can lead to incorrect results. Here are some common mistakes and how to avoid them:
Mistake 1
Not following the correct steps.
Students should follow the steps precisely: multiply the last three digits by 2, then subtract this result from the rest of the number.
Divisibility Rule of 838 Examples
Problem 1
Is 1676 divisible by 838?
Yes, 1676 is divisible by 838.
Explanation
To check if 1676 is divisible by 838, consider the specific divisibility rules or use straightforward division. If 1676 divided by 838 results in a whole number, then 1676 is divisible by 838. Here, 1676 ÷ 838 = 2, which is a whole number.
Problem 2
Can 2514 be divisible by 838 according to its divisibility rule?
No, 2514 is not divisible by 838.
Explanation
Checking if 2514 is divisible by 838, divide 2514 by 838. If the result is not a whole number, then it is not divisible. Here, 2514 ÷ 838 ≈ 3.0004, which is not a whole number.
Problem 3
Check if 3352 is divisible by 838
Yes, 3352 is divisible by 838.
Explanation
To verify if 3352 is divisible by 838, perform the division: 3352 ÷ 838. The result should be a whole number. Here, 3352 ÷ 838 = 4, confirming divisibility.
Problem 4
Determine the divisibility of 5008 by 838.
No, 5008 is not divisible by 838.
Explanation
To determine if 5008 is divisible by 838, divide 5008 by 838. If the quotient is not a whole number, it is not divisible. Here, 5008 ÷ 838 ≈ 5.976, indicating it is not divisible.
Problem 5
Is 6710 divisible by 838?
No, 6710 is not divisible by 838.
Explanation
By dividing 6710 by 838, we can check divisibility. If the division results in a whole number, it is divisible. Here, 6710 ÷ 838 ≈ 8.007, which is not a whole number.
