Divisibility Rule of 938
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 938.
What is the Divisibility Rule of 938?
The divisibility rule for 938 helps us determine if a number is divisible by 938 without performing division. To check whether a number like 1876 is divisible by 938 using this rule, follow these steps:
Step 1: Divide the number into groups, each containing three digits starting from the end. For 1876, we have the groups: 876 and 1.
Step 2: Multiply the number in the group with the least significant digits by 938. Here, 876 × 938 = 821088.
Step 3: Subtract the result from Step 2 with the number formed by the remaining groups. Here, subtract 821088 from 1: 1 - 821088 = -821087.
Step 4: If the result is 0 or a multiple of 938, then the original number is divisible by 938.
Tips and Tricks for Divisibility Rule of 938
Learning the divisibility rule can help kids master division. Here are a few tips and tricks for the divisibility rule of 938:
Know the multiples of 938:
Memorize the multiples of 938 (938, 1876, 2814, etc.) to quickly check divisibility. If the result from subtraction is a multiple of 938, then the number is divisible by 938.
Use the negative numbers:
If the result we get after subtraction is negative, 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 938. For example, check if 1876000 is divisible by 938 using the divisibility test. Divide into groups: 000 and 1876, then multiply 000 by 938 = 0. Subtract from 1876: 1876 - 0 = 1876. Since 1876 is a multiple of 938, 1876000 is divisible by 938.
Use the division method to verify:
Students can use the division method 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 938
The divisibility rule of 938 helps us quickly check if a given number is divisible by 938, but common mistakes like calculation errors lead to incorrect calculations. Here we will understand some common mistakes that will help you avoid them.
Mistake 1
Not following the correct steps.
Students should follow the correct steps by dividing the number into groups, multiplying the least significant group by 938, and subtracting the result from the remaining groups.
Divisibility Rule of 938 Examples
Problem 1
Is 2814 divisible by 938?
Yes, 2814 is divisible by 938.
Explanation
To check if 2814 is divisible by 938, we can perform the following:
1) Divide the number 2814 by 938.
2) 2814 ÷ 938 = 3, which is a whole number without any remainder.
Therefore, 2814 is divisible by 938.
Problem 2
Check the divisibility rule of 938 for 1876.
No, 1876 is not divisible by 938.
Explanation
For checking the divisibility of 1876 by 938:
1) Divide 1876 by 938.
2) 1876 ÷ 938 = 2, but there is a remainder, indicating it's not divisible.
Therefore, 1876 is not divisible by 938.
Problem 3
Is -4690 divisible by 938?
No, -4690 is not divisible by 938.
Explanation
To check if -4690 is divisible by 938:
1) Remove the negative sign and divide 4690 by 938.
2) 4690 ÷ 938 is not a whole number; it has a remainder.
Therefore, -4690 is not divisible by 938.
Problem 4
Can 469 be divisible by 938 following the divisibility rule?
No, 469 isn't divisible by 938.
Explanation
To check if 469 is divisible by 938:
1) Since 469 is less than 938, it is not divisible by 938.
Therefore, 469 is not divisible by 938.
Problem 5
Check the divisibility rule of 938 for 1876.
No, 1876 is not divisible by 938.
Explanation
To verify if 1876 is divisible by 938:
1) Divide 1876 by 938.
2) 1876 ÷ 938 = 2, but with a remainder, indicating it's not divisible.
Therefore, 1876 is not divisible by 938.
