Divisibility Rule of 308

Professor Greenline Explaining Math Concepts

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 308.

What is the Divisibility Rule of 308?

The divisibility rule for 308 is a method by which we can find out if a number is divisible by 308 or not without using the division method. Check whether 924 is divisible by 308 with the divisibility rule.

 

Step 1: Recognize that 308 is composed of the prime factors 2, 2, 7, and 11. Thus, a number divisible by 308 must be divisible by 2, 2, 7, and 11.  


Step 2: Check divisibility by 4 (2 times 2): The last two digits of 924 form 24, which is divisible by 4.  


Step 3: Check divisibility by 7: Subtract twice the last digit from the rest of the number. For 924, 4 × 2 = 8, and 92 - 8 = 84, which is divisible by 7.  


Step 4: Check divisibility by 11: Alternately subtract and add the digits. For 924, 9 - 2 + 4 = 11, which is divisible by 11.  


Since 924 is divisible by 4, 7, and 11, it is divisible by 308.

Tips and Tricks for Divisibility Rule of 308

Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 308.

 

1. Know the multiples of 308:  


Memorize some multiples of 308 (308, 616, 924, etc.) to quickly check divisibility. If the result from the checks is a multiple of 308, then the number is divisible by 308.

 

2. Use the prime factors:  


Remember the prime factorization of 308 (2, 2, 7, 11) to break down the divisibility checks into simpler parts.

 

3. Repeat the process for large numbers:  


For larger numbers, break them down and repeatedly apply the divisibility tests for 4, 7, and 11 until a conclusion is reached.

 

4. Use the division method to verify:  


Students can use the division method to verify and cross-check their results. This will help them confirm their understanding.

Problem 1

Is 1232 divisible by 308?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

 No, 1232 is not divisible by 308.
 

Explanation

To check if 1232 is divisible by 308, we can use a direct division approach because 308 doesn’t have a simple small-factor divisibility rule. Dividing 1232 by 308 gives approximately 4.00, indicating it's not an integer, hence 1232 is not divisible by 308.
