Divisibility Rule of 384
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 items. In this topic, we will learn about the divisibility rule of 384.
What is the Divisibility Rule of 384?
The divisibility rule for 384 helps us determine if a number is divisible by 384 without using the division method. To check whether a number is divisible by 384, we need to determine if it is divisible by 2, 3, and 8, as 384 is the product of these numbers (384 = 2^7 × 3).
Step 1: Check divisibility by 2. A number is divisible by 2 if its last digit is even.
Step 2: Check divisibility by 3. Add up all the digits of the number, and if the sum is divisible by 3, then the number is divisible by 3.
Step 3: Check divisibility by 8. A number is divisible by 8 if the last three digits form a number that is divisible by 8.
Example: Check whether 768 is divisible by 384.
Step 1: Check divisibility by 2. The last digit of 768 is 8, which is even, so it is divisible by 2.
Step 2: Check divisibility by 3. The sum of the digits of 768 is 7 + 6 + 8 = 21, and 21 is divisible by 3.
Step 3: Check divisibility by 8. The last three digits of 768 are 768, and 768 ÷ 8 = 96, which is an integer. Therefore, 768 is divisible by 8.
Since 768 is divisible by 2, 3, and 8, it is also divisible by 384.
Tips and Tricks for Divisibility Rule of 384
Learning the divisibility rule helps students master division. Let's explore a few tips and tricks for the divisibility rule of 384.
- Understand the factors: Recognize that 384 is composed of the factors 2, 3, and 8. Ensure a number meets all these divisibility conditions.
- Practice with multiples: Familiarize yourself with multiples of 384 (e.g., 384, 768, 1152) to quickly assess divisibility.
- Double-check with smaller factors: If a number passes divisibility checks for 2, 3, and 8, it is divisible by 384.
- Use the division method to verify: Students can use actual division to verify and cross-check their results, which helps reinforce their understanding.
Common Mistakes and How to Avoid Them in Divisibility Rule of 384
The divisibility rule of 384 allows us to quickly check if a number is divisible by 384, but common mistakes can occur. Here's how to avoid them:
Mistake 1
Not checking all factors.
Ensure the number is divisible by 2, 3, and 8.
Divisibility Rule of 384 Examples
Problem 1
Is 1920 divisible by 384?
Yes, 1920 is divisible by 384.
Explanation
To determine if 1920 is divisible by 384, follow these steps:
1) Check if 1920 is divisible by 2. The last digit is 0, so it is divisible by 2.
2) Check if 1920 is divisible by 3. Add the digits, 1 + 9 + 2 + 0 = 12, which is divisible by 3.
3) Check if 1920 is divisible by 8. The last three digits are 920, which is not divisible by 8.
Since the divisibility fails at step 3, 1920 is not divisible by 384.
Problem 2
