3 <p>The divisibility rule is a way to determine whether a number is divisible by another number without performing the division operation. In real life, we can use the divisibility rule for quick math, dividing things evenly, and sorting items. In this topic, we will learn about the divisibility rule of 397.</p>

4 <h2>What is the Divisibility Rule of 397?</h2>

5 <p>The<a>divisibility rule</a>for 397 is a method by which we can ascertain if a<a>number</a>is divisible by 397 without performing the<a>division</a>directly. Check whether 15881 is divisible by 397 using the divisibility rule.</p>

6 <p><strong>Step 1:</strong>Multiply the last digit<a>of</a>the number by 17. In 15881, 1 is the last digit, so multiply it by 17. 1 × 17 = 17.</p>

7 <p><strong>Step 2:</strong>Subtract the result from Step 1 from the remaining part of the number, excluding the last digit. That is, 1588 - 17 = 1571.</p>

8 <p><strong>Step 3:</strong>Repeat the process for the result if necessary. For 1571, multiply the last digit (1) by 17, 1 × 17 = 17. Subtract from the remaining digits 157 - 17 = 140.</p>

9 <p><strong>Step 4:</strong>Continue the process if necessary, but for this example, since 140 is not divisible by 397, 15881 is not divisible by 397.</p>

10 <h2>Tips and Tricks for Divisibility Rule of 397</h2>

11 <p>Learning the divisibility rule helps kids master division. Let’s learn a few tips and tricks for the divisibility rule of 397.</p>

12 <ul><li><strong>Know the<a>multiples</a>of 397:</strong> Memorize the multiples of 397 (397, 794, 1191, 1588, etc.) to quickly check divisibility. If the result from the<a>subtraction</a>is a multiple of 397, then the number is divisible by 397. </li>

13 <li><strong>Use the<a>negative numbers</a>:</strong> If the result after subtraction is negative, consider its<a>absolute value</a>for checking divisibility. </li>

14 <li><strong>Repeat the process for large numbers: </strong>Students should keep repeating the divisibility process until they reach a small number that is divisible by 397 or can clearly determine divisibility. </li>

15 <li><strong>Use the division method to verify:</strong> Students can use the division method as a way to verify and cross-check their results. This will help them to confirm their findings and also learn.</li>

16 </ul><h2>Common Mistakes and How to Avoid Them in Divisibility Rule of 397</h2>

17 <p>The divisibility rule of 397 helps us quickly check if a given number is divisible by 397, but common mistakes like calculation errors can lead to incorrect results. Here, we will understand some common mistakes and how to avoid them.</p>
