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 28.</p>

4 <h2>What is the Divisibility Rule of 28?</h2>

5 <p>The<a>divisibility rule</a>for 28 is a method by which we can find out if a<a>number</a>is divisible by 28 or not without using the<a>division</a>method.</p>

6 <p>Check whether 196 is divisible by 28 with the divisibility rule.</p>

7 <p><strong>Step 1:</strong>Check if the number is divisible by 4. The last two digits of 196 are 96, which is divisible by 4.</p>

8 <p><strong>Step 2:</strong>Check if the number is divisible by 7 using the divisibility rule of 7. For 196, multiply the last digit by 2 (6 × 2 = 12) and subtract it from the remaining digits (19 - 12 = 7), which is a<a>multiple</a>of 7.</p>

9 <p>Since 196 passes both conditions (divisible by 4 and 7), it is divisible by 28.</p>

10 <h2>Tips and Tricks for Divisibility Rule of 28</h2>

11 <p>Learn divisibility rules to help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 28.</p>

12 <ul><li><strong>Know the multiples of 28:</strong>Memorize the multiples of 28 (28, 56, 84, 112, 140… etc.) to quickly check the divisibility. If the number matches any of the multiples, it is divisible by 28. </li>

13 <li><strong>Use<a>negative numbers</a>carefully:</strong>If the result obtained during the process is negative, consider it as positive when checking for divisibility. </li>

14 <li><strong>Repeat the process for large numbers</strong>: Students should keep repeating the divisibility process for both 4 and 7 until they reach a small number that is divisible by both.<p>For example, check if 392 is divisible by 28 using the divisibility test. </p>

15 <p>First, check for divisibility by 4: The last two digits are 92, which is divisible by 4.</p>

16 <p>Next, check for divisibility by 7: Multiply the last digit by 2 (2 × 2 = 4) and subtract it from the remaining digits (39 - 4 = 35), which is a multiple of 7.</p>

17 <p> Since 392 satisfies both conditions, it is divisible by 28.</p>

18 </li>

19 <li><strong>Use the division method to verify:</strong>Students can use the division method as a way to verify and crosscheck their results. This helps them verify and also learn.</li>

20 </ul><h2>Common Mistakes and How to Avoid Them in Divisibility Rule of 28</h2>

21 <p>The divisibility rule of 28 helps us to quickly check if the given number is divisible by 28, but common mistakes like calculation errors lead to incorrect results. Here we will understand some common mistakes that will help you to avoid them.</p>

24 <h3>Problem 1</h3>

25 <p>Is 196 divisible by 28?</p>

26 <p>Okay, lets begin</p>

27 <p>Yes, 196 is divisible by 28.</p>

28 <h3>Explanation</h3>

29 <p>To determine if 196 is divisible by 28, we can use a combination of divisibility rules for 4 and 7, since 28 = 4 × 7.</p>

30 <p>1) Check divisibility by 4: The last two digits of 196 are 96, which is divisible by 4 (96 ÷ 4 = 24).</p>

31 <p>2) Check divisibility by 7: Use the rule for 7. Multiply the last digit by 2, 6 × 2 = 12, and subtract from the remaining part, 19 - 12 = 7, which is a multiple of 7.</p>

32 <p>Since 196 meets divisibility rules for both 4 and 7, it is divisible by 28.</p>

33 <p>Well explained 👍</p>

34 <h3>Problem 2</h3>

35 <p>Check if 364 is divisible by 28.</p>

36 <p>Okay, lets begin</p>

37 <p>Yes, 364 is divisible by 28.</p>

38 <h3>Explanation</h3>

39 <p>We need to check divisibility by both 4 and 7.</p>

40 <p>1) Divisibility by 4: The last two digits, 64, are divisible by 4 (64 ÷ 4 = 16).</p>

41 <p>2) Divisibility by 7: Multiply the last digit by 2, 4 × 2 = 8, and subtract from the rest, 36 - 8 = 28, which is divisible by 7.</p>

42 <p>Since 364 is divisible by both 4 and 7, it is divisible by 28.</p>

43 <p>Well explained 👍</p>

44 <h3>Problem 3</h3>

45 <p>Is 308 divisible by 28?</p>

46 <p>Okay, lets begin</p>

47 <p>Yes, 308 is divisible by 28.</p>

48 <h3>Explanation</h3>

49 <p>Check for divisibility by 4 and 7.</p>

50 <p>1) Divisibility by 4: The last two digits are 08, which is divisible by 4 (8 ÷ 4 = 2).</p>

51 <p>2) Divisibility by 7: Multiply the last digit by 2, 8 × 2 = 16, and subtract from the rest, 30 - 16 = 14, which is divisible by 7.</p>

52 <p>Thus, 308 is divisible by 28.</p>

53 <p>Well explained 👍</p>

54 <h3>Problem 4</h3>

55 <p>Can 250 be divisible by 28?</p>

56 <p>Okay, lets begin</p>

57 <p>No, 250 is not divisible by 28.</p>

58 <h3>Explanation</h3>

59 <p>Check divisibility by 4 and 7.</p>

60 <p>1) Divisibility by 4: The last two digits, 50, are not divisible by 4.</p>

61 <p>2) Divisibility by 7: Multiply the last digit by 2, 0 × 2 = 0, and subtract from the rest, 25 - 0 = 25, which is not divisible by 7.</p>

62 <p>Since 250 is not divisible by both 4 and 7, it is not divisible by 28.</p>

63 <p>Well explained 👍</p>

64 <h3>Problem 5</h3>

65 <p>Check if 784 is divisible by 28.</p>
