Divisibility Rule of 192
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 192.
What is the Divisibility Rule of 192?
The divisibility rule for 192 is a method by which we can find out if a number is divisible by 192 or not without using the division method. Check whether 384 is divisible by 192 with the divisibility rule.
Step 1: Check if the number is divisible by 2, 3, and 32. The number must meet all these criteria to be divisible by 192.
For divisibility by 2, the last digit of 384 is 4, which is even. Therefore, 384 is divisible by 2.
For divisibility by 3, sum the digits: 3 + 8 + 4 = 15, which is divisible by 3.
For divisibility by 32, the last five digits must form a number that is divisible by 32. Here, 384 has only three digits, but 384 ÷ 32 = 12, which is a whole number.
Since 384 meets all these conditions, it is divisible by 192.

Tips and Tricks for Divisibility Rule of 192
Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 192.
- Know the multiples of 192: Memorize the multiples of 192 (192, 384, 576, 768, etc.) to quickly check divisibility.
- Use smaller checks: Instead of dividing directly by 192, check for divisibility by 2, 3, and 32 separately.
- Repeat the process for larger numbers: Students should keep repeating the divisibility process for each condition (2, 3, and 32) until they confirm the number meets all criteria.
- 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 192
The divisibility rule of 192 helps us quickly check if a given number is divisible by 192, but common mistakes like calculation errors lead to incorrect conclusions. Here we will understand some common mistakes and solutions.
Mistake 1
Not following the correct steps.
Students should ensure they check divisibility by 2, 3, and 32 sequentially and completely.
Mistake 2
Miscalculating sums or checks.
Double-check calculations for sums of digits and divisibility tests to avoid errors.
Mistake 3
Forgetting to check all conditions.
Remember that a number must satisfy divisibility by 2, 3, and 32 to be divisible by 192.
Mistake 4
Using incorrect multiples.
Familiarize yourself with the correct multiples of 192 to avoid mistakes.
Mistake 5
Confusing the steps.
Practice regularly to memorize and understand the steps involved.

Divisibility Rule of 192 Examples
Problem 1
Is 3840 divisible by 192?
Yes, 3840 is divisible by 192.
Explanation
To check if 3840 is divisible by 192, we need to test as follows:
1) Divide the number by 2 repeatedly until it is no longer even. 3840 ÷ 2 = 1920, 1920 ÷ 2 = 960, 960 ÷ 2 = 480, 480 ÷ 2 = 240, 240 ÷ 2 = 120, 120 ÷ 2 = 60.
2) Now, check if 60 is divisible by 3 (since 192 = 2^6 × 3). Sum the digits of 60, 6 + 0 = 6.
3) Since 6 is divisible by 3, the original number 3840 is divisible by 192.
Problem 2
Check the divisibility rule of 192 for 768.
Yes, 768 is divisible by 192.
Explanation
Let's determine if 768 is divisible by 192:
1) Divide by 2 repeatedly until the number is no longer even: 768 ÷ 2 = 384, 384 ÷ 2 = 192.
2) We reach 192, which is exactly equal to 192, confirming that 768 is divisible by 192.
Problem 3
Is 576 divisible by 192?
Yes, 576 is divisible by 192.
Explanation
To verify divisibility by 192 for 576:
1) Divide by 2 repeatedly: 576 ÷ 2 = 288, 288 ÷ 2 = 144.
2) Check if 144 is divisible by 3 by summing the digits: 1 + 4 + 4 = 9.
3) Since 9 is divisible by 3, 144 is divisible by 3, confirming that 576 is divisible by 192.
Problem 4
Can 500 be divisible by 192 following the divisibility rule?
No, 500 is not divisible by 192.
Explanation
To check 500 for divisibility by 192:
1) Divide by 2 until no longer even: 500 ÷ 2 = 250, 250 ÷ 2 = 125.
2) Check if 125 is divisible by 3: 1 + 2 + 5 = 8.
3) Since 8 is not divisible by 3, 500 is not divisible by 192.
Problem 5
Check the divisibility rule of 192 for 960.
Yes, 960 is divisible by 192.
Explanation
To check divisibility by 192 for 960:
1) Divide by 2: 960 ÷ 2 = 480, 480 ÷ 2 = 240, 240 ÷ 2 = 120.
2) Check if 120 is divisible by 3: 1 + 2 + 0 = 3.
3) Since 3 is divisible by 3, 120 is divisible by 3, confirming that 960 is divisible by 192.
