3 <p>Factors are the numbers that divide any given number evenly without a 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 585, how they are used in real life, and tips to learn them quickly.</p>

4 <h2>What are the Factors of 585?</h2>

5 <p>The<a>numbers</a>that divide 585 evenly are known as<a>factors</a>of 585.</p>

6 <p>A factor of 585 is a number that divides the number without<a>remainder</a>.</p>

7 <p>The factors of 585 are 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, and 585.</p>

8 <p><strong>Negative factors of 585:</strong>-1, -3, -5, -9, -13, -15, -39, -45, -65, -117, -195, and -585.</p>

9 <p><strong>Prime factors of 585:</strong>3, 5, and 13.</p>

10 <p><strong>Prime factorization of 585:</strong>3 × 3 × 5 × 13 or \(32 times 5 times 13).</p>

11 <p>The<a>sum</a>of factors of 585: 1 + 3 + 5 + 9 + 13 + 15 + 39 + 45 + 65 + 117 + 195 + 585 = 1092</p>

12 <h2>How to Find Factors of 585?</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<a>division</a>method</li>

16 <li>Prime factors and Prime factorization</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 585. Identifying the numbers which are multiplied to get the number 585 is the multiplication method.</p>

19 <p><strong>Step 1:</strong>Multiply 585 by 1, 585 × 1 = 585.</p>

20 <p><strong>Step 2:</strong>Check for other numbers that give 585 after multiplying </p>

21 <p>3 × 195 = 585 </p>

22 <p>5 × 117 = 585 </p>

23 <p>9 × 65 = 585 </p>

24 <p>13 × 45 = 585 </p>

25 <p>15 × 39 = 585</p>

26 <p>Therefore, the positive factor pairs of 585 are: (1, 585), (3, 195), (5, 117), (9, 65), (13, 45), and (15, 39). For every positive factor, there is a negative factor.</p>

62 <p>There are 9 boxes and 585 marbles. How will the marbles be divided equally?</p>

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

64 <p>They will get 65 marbles each.</p>

65 <h3>Explanation</h3>

66 <p>To divide the marbles equally, we need to divide the total marbles by the number of boxes.</p>

70 <p>A garden is rectangular, the length of the garden is 13 meters, and the total area is 585 square meters. Find the width.</p>

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

72 <p>45 meters.</p>

73 <h3>Explanation</h3>

74 <p>To find the width of the garden, we use the formula,</p>

75 <p>Area = length × width</p>

76 <p>585 = 13 × width</p>

77 <p>To find the value of width, we need to shift 13 to the left side.</p>

78 <p>585/13 = width</p>

79 <p>Width = 45.</p>
