Divisibility Rule of 388
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 388.
What is the Divisibility Rule of 388?
The divisibility rule for 388 is a method by which we can find out if a number is divisible by 388 or not without using the division method. Check whether 1164 is divisible by 388 with this divisibility rule.
Step 1: Check if the number is divisible by 2, 4, and 97. If it is divisible by these three numbers, then it is divisible by 388. For 1164, check divisibility by 2, 4, and 97.
Step 2: 1164 is even, so it is divisible by 2. Then check divisibility by 4: the last two digits are 64, and 64 is divisible by 4. Finally, check divisibility by 97: divide 1164 by 97, which equals 12 with no remainder.
Step 3: Since the number is divisible by 2, 4, and 97, therefore, the number is divisible by 388.
Tips and Tricks for Divisibility Rule of 388
Learning the divisibility rule will help kids to master division. Let’s learn a few tips and tricks for the divisibility rule of 388.
- Know the multiples of 388: Memorize the multiples of 388 (388, 776, 1164, 1552, etc.) to quickly check the divisibility. If the result from the division is a whole number, then the number is divisible by 388.
- Use the divisibility of smaller factors: If a number is divisible by 2, 4, and 97, it is divisible by 388. Use this to your advantage.
- Repeat the process for large numbers: Students should keep repeating the divisibility process for 2, 4, and 97 until they confirm divisibility by 388. For example, check if 2716 is divisible by 388. First, check divisibility by 2: 2716 is even. Then check divisibility by 4: the last two digits are 16, which is divisible by 4. Finally, check divisibility by 97: divide 2716 by 97, which equals 28 with no remainder. Thus, 2716 is divisible by 388.
- 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 388
The divisibility rule of 388 helps us to quickly check if the given number is divisible by 388, but common mistakes like calculation errors lead to incorrect calculations. Here we will understand some common mistakes that will help you to understand.
Mistake 1
Not checking divisibility by all factors.
Students should ensure they check divisibility by 2, 4, and 97, as skipping any could lead to incorrect results.
Mistake 2
Misapplying the rules for smaller numbers.
Students should remember that the rules for 2, 4, and 97 must be applied correctly to ensure divisibility by 388.
Mistake 3
Not repeating the process for large numbers.
Students often stop the process too early. The process should be repeated until all factors are confirmed.
Mistake 4
Overlooking simple errors.
Students should carefully perform each step and verify each part of the process to avoid simple errors.
Mistake 5
Confusing the steps.
Students often confuse the steps or forget them, so they should practice regularly to avoid errors.
Divisibility Rule of 388 Examples
Problem 1
Is 1164 divisible by 388?
Yes, 1164 is divisible by 388.
Explanation
Let's apply a hypothetical divisibility rule for 388:
1) Divide the number into groups of three digits starting from the right: 164 and 1.
2) Add each group: 164 + 1 = 165.
3) If 165 is divisible by 388, then 1164 is divisible by 388. Since 165 is not divisible by 388, 1164 is not divisible by 388. Upon rechecking, it's found that 1164 is indeed divisible by 388 without a remainder.
Problem 2
Check the divisibility rule of 388 for 2328.
Yes, 2328 is divisible by 388.
Explanation
Let's apply a hypothetical divisibility rule for 388:
1) Divide the number into groups of three digits starting from the right: 328 and 2.
2) Add each group: 328 + 2 = 330.
3) If 330 is divisible by 388, then 2328 is divisible by 388. Since 330 is not divisible by 388, upon rechecking, it's confirmed that 2328 is divisible by 388 without a remainder.
Problem 3
Is -776 divisible by 388?
Yes, -776 is divisible by 388.
Explanation
To check if -776 is divisible by 388, consider the positive number 776.
1) Divide the number into groups of three digits starting from the right: 776.
2) Since there is only one group, check if 776 is divisible by 388 directly.
3) Yes, 776 divided by 388 equals 2, with no remainder. Therefore, -776 is divisible by 388.
Problem 4
Can 582 be divisible by 388 following the divisibility rule?
No, 582 isn't divisible by 388.
Explanation
Let's apply a hypothetical divisibility rule for 388:
1) Divide the number into groups of three digits starting from the right: 582.
2) Since there is only one group, check if 582 is divisible by 388 directly.
3) 582 divided by 388 doesn't result in an integer, so 582 is not divisible by 388.
Problem 5
Check the divisibility rule of 388 for 3104.
Yes, 3104 is divisible by 388.
Explanation
Let's apply a hypothetical divisibility rule for 388:
1) Divide the number into groups of three digits starting from the right: 104 and 3.
2) Add each group: 104 + 3 = 107.
3) If 107 is divisible by 388, then 3104 is divisible by 388. Since 107 is not divisible by 388, upon rechecking, it's confirmed that 3104 is divisible by 388 without a remainder.
