Divisibility Rule of 187
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 187. 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 187.
What is the Divisibility Rule of 187?
The divisibility rule for 187 is a method by which we can find out if a number is divisible by 187 or not without using the division method. Check whether 561 is divisible by 187 with the divisibility rule.
Step 1: Check if the number is divisible by 11 and 17, as these are the prime factors of 187.
Step 2: To check divisibility by 11, sum the digits in odd positions and even positions separately, then find the difference. If the difference is a multiple of 11 (including zero), it’s divisible by 11. For 561, (5+1) - 6 = 0, which is divisible by 11.
Step 3: To check divisibility by 17, subtract 5 times the last digit from the rest of the number. For 561, 56 - (5×1) = 51. Since 51 is not divisible by 17, 561 is not divisible by 187.

Tips and Tricks for Divisibility Rule of 187
Learn divisibility rules to help master division. Let’s learn a few tips and tricks for the divisibility rule of 187.
- Know the multiples of 11 and 17: Memorize the multiples of 11 (11, 22, 33,...) and 17 (17, 34, 51,...) to quickly check divisibility. If the number passes both checks, it’s divisible by 187.
- Use negative numbers: If the result from subtraction is negative, consider the absolute value for checking divisibility.
- Repeat the process for large numbers: Keep repeating the divisibility process for large numbers until you reach a small number that is divisible by 11 and 17. For example, check if 3183 is divisible by 187 using the divisibility test.
For 11: (3+8) - (1+3) = 7, which is not divisible by 11.
For 17: 318 - (5×3) = 303. Repeat: 30 - (5×3) = 15, which is not divisible by 17.
- Use the division method to verify: Use the division method to verify and crosscheck results, helping ensure accuracy and understanding.
Common Mistakes and How to Avoid Them in Divisibility Rule of 187
The divisibility rule of 187 helps us quickly check if a number is divisible by 187, but common mistakes like calculation errors can lead to incorrect results. Here, we will understand some common mistakes and how to avoid them.
Mistake 1
Not following both divisibility checks.
Ensure you check both 11 and 17 as these are the prime factors of 187.
Mistake 2
Incorrect subtraction for 17.
Remember to multiply the last digit by 5 and subtract from the rest of the number.
Mistake 3
Not repeating the process for large numbers.
Continue the process until reaching a smaller number to confirm divisibility.
Mistake 4
Overlooking negative results.
Consider the absolute value for checking divisibility with negative results.
Mistake 5
Confusing the steps.
Practice regularly to become familiar with the steps and avoid errors.
