3 <p>The divisibility rule is a way to determine whether a number is divisible by another number without performing division. 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 279.</p>

4 <h2>What is the Divisibility Rule of 279?</h2>

5 <p>The<a>divisibility rule</a>for 279 is a method by which we can determine if a<a>number</a>is divisible by 279 without performing<a>division</a>. Let's check whether 83769 is divisible by 279 using this rule.</p>

6 <p><strong>Step 1:</strong>Divide the number into groups<a>of</a>three digits from the right. In 83769, we have 069 and 083.</p>

7 <p><strong>Step 2:</strong>Sum these groups: 69 + 83 = 152.</p>

8 <p><strong>Step 3:</strong>If the result is a<a>multiple</a>of 279, then the number is divisible by 279. Since 152 is not a multiple of 279, 83769 is not divisible by 279.</p>

9 <h2>Tips and Tricks for the Divisibility Rule of 279</h2>

10 <p>Learning the divisibility rule helps students master division. Here are a few tips and tricks for the divisibility rule of 279.</p>

11 <ul><li><strong>Know the multiples of 279:</strong>Memorize the multiples of 279 (279, 558, 837, etc.) to quickly check divisibility. If the<a>sum</a>from step 2 is a multiple of 279, then the number is divisible by 279. </li>

12 <li><strong>Use the negative values:</strong>If the sum after adding the groups is negative, consider it as positive for checking divisibility. </li>

13 <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 279. For example, check if 756837 is divisible by 279 using the divisibility test. Divide into groups: 837 and 756. Sum these groups: 837 + 756 = 1593. Since 1593 is still large, repeat the process: 593 + 1 = 594. Since 594 is not a multiple of 279, 756837 is not divisible by 279. </li>

14 <li><strong>Use the division method to verify:</strong>Students can use the division method to verify and cross-check their results, which will help them confirm and learn. </li>

15 </ul><h2>Common Mistakes and How to Avoid Them in the Divisibility Rule of 279</h2>

16 <p>The divisibility rule of 279 helps us quickly check if a given number is divisible by 279, but common mistakes, like calculation errors, can lead to incorrect results. Here, we will understand some common mistakes that will help you avoid them.</p>

19 <h3>Problem 1</h3>

20 <p>Is 837 divisible by 279?</p>

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

22 <p>Yes, 837 is divisible by 279. </p>

23 <h3>Explanation</h3>

24 <p>To check for divisibility by 279, follow these steps: </p>

25 <p>1) Take the last digit, multiply it by 9: 7 × 9 = 63.</p>

26 <p> 2) Add this result to the rest of the number: 83 + 63 = 146.</p>

27 <p> 3) Repeat the process for 146: 6 × 9 = 54, 14 + 54 = 68. </p>

28 <p>4) 68 is not divisible by 279. However, since the original sum resulted in a multiple of 279, 837 is divisible by 279.</p>

29 <p>Well explained 👍</p>

30 <h3>Problem 2</h3>

31 <p>Check the divisibility rule of 279 for 558.</p>

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

33 <p>Yes, 558 is divisible by 279. </p>

34 <h3>Explanation</h3>

35 <p>Applying the divisibility rule for 279:</p>

36 <p> 1) Multiply the last digit by 9: 8 × 9 = 72. </p>

37 <p>2) Add this result to the remaining digits: 55 + 72 = 127. </p>

38 <p>3) Since 127 is divisible by 279, 558 is also divisible by 279.</p>

39 <p>Well explained 👍</p>

40 <h3>Problem 3</h3>

41 <p>Is 2016 divisible by 279?</p>

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

43 <p>No, 2016 is not divisible by 279. </p>

44 <h3>Explanation</h3>

45 <p>To determine divisibility by 279: </p>

46 <p>1) Multiply the last digit by 9: 6 × 9 = 54. </p>

47 <p>2) Add this result to the rest of the number: 201 + 54 = 255. </p>

48 <p>3) Since 255 is not divisible by 279, 2016 is not divisible by 279.</p>

49 <p>Well explained 👍</p>

50 <h3>Problem 4</h3>

51 <p>Can 1395 be divisible by 279?</p>

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

53 <p>Yes, 1395 is divisible by 279. </p>

54 <h3>Explanation</h3>

55 <p>Checking divisibility by 279: 1) Multiply the last digit by 9: 5 × 9 = 45. 2) Add this result to the remaining digits: 139 + 45 = 184. 3) Since 184 is divisible by 279, 1395 is divisible by 279. </p>

56 <p>Well explained 👍</p>

57 <h3>Problem 5</h3>

58 <p>Check the divisibility rule of 279 for 5580.</p>

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

60 <p>Yes, 5580 is divisible by 279. </p>

61 <h3>Explanation</h3>

62 <p>To verify divisibility by 279:</p>

63 <p> 1) Multiply the last digit by 9: 0 × 9 = 0.</p>

64 <p> 2) Add this result to the rest of the number: 558 + 0 = 558. </p>

65 <p>3) Further check 558: 8 × 9 = 72, 55 + 72 = 127. </p>

66 <p>4) Since 127 is not divisible by 279, the original number 5580 is divisible by 279 because it ultimately resulted in 558, which is a multiple of 279.</p>
