3 <p>Factors are the numbers that divide any given number evenly without remainder. In daily life, we use factors for tasks like sharing items equally, arranging things, etc. In this topic, we will learn about the factors of 686, how they are used in real life, and tips to learn them quickly.</p>

4 <h2>What are the Factors of 686?</h2>

5 <p>The<a>numbers</a>that divide 686 evenly are known as<a>factors</a><a>of</a>686.</p>

6 <p>A factor of 686 is a number that divides the number without<a>remainder</a>.</p>

7 <p>The factors of 686 are 1, 2, 7, 14, 49, 98, 343, and 686.</p>

8 <p><strong>Negative factors of 686:</strong>-1, -2, -7, -14, -49, -98, -343, and -686.</p>

9 <p><strong>Prime factors of 686:</strong>2 and 7.</p>

10 <p><strong>Prime factorization of 686:</strong>2 × 7³.</p>

11 <p>The<a>sum</a>of factors of 686: 1 + 2 + 7 + 14 + 49 + 98 + 343 + 686 = 1200</p>

12 <h2>How to Find Factors of 686?</h2>

13 <p>Factors can be found using different methods. Mentioned below are some commonly used methods:</p>

14 <ul><li>Finding factors using<a>multiplication</a> </li>

15 <li>Finding factors using the<a>division</a>method </li>

16 <li>Prime factors and<a>prime factorization</a></li>

17 </ul><h3>Finding Factors Using Multiplication</h3>

18 <p>To find factors using multiplication, we need to identify the pairs of numbers that are multiplied to give 686. Identifying the numbers which are multiplied to get the number 686 is the multiplication method.</p>

19 <p><strong>Step 1:</strong>Multiply 686 by 1, 686 × 1 = 686.</p>

20 <p><strong>Step 2:</strong>Check for other numbers that give 686 after multiplying 2 × 343 = 686 7 × 98 = 686 14 × 49 = 686</p>

21 <p>Therefore, the positive factor pairs of 686 are: (1, 686), (2, 343), (7, 98), (14, 49).</p>

22 <p>All these factor pairs result in 686. For every positive factor, there is a negative factor.</p>

56 <h3>Problem 1</h3>

57 <p>There are 7 teams and 686 balls. How will they distribute them equally?</p>

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

59 <p>They will give 98 balls to each team.</p>

60 <h3>Explanation</h3>

61 <p>To divide the balls equally, we need to divide the total balls by the number of teams.</p>

64 <h3>Problem 2</h3>

65 <p>A hall is rectangular, the length of the hall is 14 meters and the total area is 686 square meters. Find the width.</p>

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

67 <p>49 meters.</p>

68 <h3>Explanation</h3>

69 <p>To find the width of the hall, we use the formula,</p>

70 <p>Area = length × width</p>

71 <p>686 = 14 × width</p>

72 <p>To find the value of width, we need to shift 14 to the left side.</p>

73 <p>686/14 = width</p>

74 <p>Width = 49.</p>
