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 1209, how they are used in real life, and tips to learn them quickly.</p>

4 <h2>What are the Factors of 1209?</h2>

5 <p>The<a>numbers</a>that divide 1209 evenly are known as<a>factors</a>of 1209.</p>

6 <p>A factor of 1209 is a number that divides the number without a<a>remainder</a>.</p>

7 <p>The factors of 1209 are 1, 3, 13, 39, 31, 93, 403, and 1209.</p>

8 <p>Negative factors of 1209: -1, -3, -13, -31, -39, -93, -403, and -1209.</p>

9 <p>Prime factors of 1209: 3, 13, and 31.</p>

10 <p>Prime factorization of 1209: 3 × 13 × 31.</p>

11 <p>The<a>sum</a>of factors of 1209: 1 + 3 + 13 + 31 + 39 + 93 + 403 + 1209 = 1792</p>

12 <h3>How to Find Factors of 1209?</h3>

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 1209. Identifying the numbers which are multiplied to get the number 1209 is the multiplication method.</p>

19 <p><strong>Step 1:</strong>Multiply 1209 by 1, 1209 × 1 = 1209.</p>

20 <p><strong>Step 2:</strong>Check for other numbers that give 1209 after multiplying</p>

21 <p>3 × 403 = 1209</p>

22 <p>13 × 93 = 1209</p>

23 <p>31 × 39 = 1209</p>

24 <p>Therefore, the positive factor pairs of 1209 are: (1, 1209), (3, 403), (13, 93), (31, 39). For every positive factor, there is a negative factor.</p>

55 <h3>Problem 1</h3>

56 <p>There are 93 students and 1209 candies. How will they divide them equally?</p>

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

58 <p>They will get 13 candies each.</p>

59 <h3>Explanation</h3>

60 <p>To divide the candies equally, we need to divide the total candies by the number of students.</p>

64 <p>A garden is rectangular, the length of the garden is 39 meters and the total area is 1209 square meters. Find the width?</p>

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

66 <p>31 meters.</p>

67 <h3>Explanation</h3>

68 <p>To find the width of the garden, we use the formula, Area = length × width</p>

69 <p>1209 = 39 × width</p>

70 <p>To find the value of the width, we need to shift 39 to the left side.</p>
