3 <p>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 61.</p>

4 <h2>What is the Divisibility Rule of 61?</h2>

5 <p>The<a>divisibility rule</a>for 61 is a method by which we can determine if a<a>number</a>is divisible by 61 without using the<a>division</a>method. Check whether 2442 is divisible by 61 with the divisibility rule.</p>

6 <p><strong>Step 1</strong>: Multiply the last digit of the number by 2, here in 2442, 2 is the last digit. Multiply it by 2. 2 × 2 = 4.</p>

7 <p><strong>Step 2</strong>: Subtract the result from Step 1 from the remaining values but do not include the last digit. i.e., 244-4 = 240.</p>

8 <p><strong>Step 3</strong>: As 240 is not a<a>multiple</a>of 61, 2442 is not divisible by 61. If the result from Step 2 were a multiple of 61, then the number would be divisible by 61.</p>

9 <h2>Tips and Tricks for Divisibility Rule of 61</h2>

10 <p>Learning the divisibility rule will help kids to master division. Let’s learn a few tips and tricks for the divisibility rule of 61.</p>

11 <h3><strong>Know the multiples of 61: </strong></h3>

12 <p>Memorize the multiples of 61 (61, 122, 183, 244, 305, etc.) to quickly check divisibility. If the result from the<a>subtraction</a>is a multiple of 61, then the number is divisible by 61.</p>

13 <h3><strong>Use the<a>negative numbers</a>: </strong></h3>

14 <p>If the result we get after the subtraction is negative, we will avoid the<a>symbol</a>and consider it as positive for checking the divisibility of a number.</p>

15 <h3><strong>Repeat the process for large numbers: </strong></h3>

16 <p>Students should keep repeating the divisibility process until they reach a small number that is clearly divisible by 61. <strong>For example</strong>: Check if 3721 is divisible by 61 using the divisibility test. Multiply the last digit by 2, i.e., 1 × 2 = 2. Subtract the remaining digits excluding the last digit by 2, 372-2 = 370. Still, 370 is a large number, hence we will repeat the process again and multiply the last digit by 2, 0 × 2 = 0. Now subtracting 0 from the remaining numbers excluding the last digit, 37-0 = 37. 37 is not a multiple of 61, so 3721 is not divisible by 61.</p>

17 <h3><strong>Use the division method to verify: </strong></h3>

18 <p>Students can use the division method as a way to verify and cross-check their results. This will help them to verify and also learn.</p>

19 <h2>Common Mistakes and How to Avoid Them in Divisibility Rule of 61</h2>

20 <p>The divisibility rule of 61 helps us to quickly check if a given number is divisible by 61, but common mistakes like calculation errors lead to incorrect conclusions. Here we will understand some common mistakes that will help you to avoid them.</p>
