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

4 <h2>What are the Factors of 855?</h2>

5 <p>The<a>numbers</a>that divide 855 evenly are known as<a>factors</a>of 855.</p>

6 <p>A factor of 855 is a number that divides the number without<a>remainder</a>.</p>

7 <p>The factors of 855 are 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, and 855.</p>

8 <p>Negative factors of 855: -1, -3, -5, -9, -15, -19, -45, -57, -95, -171, -285, and -855.</p>

10 <p>Prime factorization of 855: 3 × 3 × 5 × 19.</p>

11 <p>The<a>sum</a>of factors of 855: 1 + 3 + 5 + 9 + 15 + 19 + 45 + 57 + 95 + 171 + 285 + 855 = 1560</p>

12 <h2>How to Find Factors of 855?</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<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 855. Identifying the numbers which are multiplied to get the number 855 is the multiplication method.</p>

19 <p><strong>Step 1:</strong>Multiply 855 by 1, 855 × 1 = 855.</p>

20 <p><strong>Step 2:</strong>Check for other numbers that give 855 after multiplying</p>

21 <p>3 × 285 = 855</p>

22 <p>5 × 171 = 855</p>

23 <p>9 × 95 = 855</p>

24 <p>15 × 57 = 855</p>

25 <p>19 × 45 = 855</p>

26 <p>Therefore, the positive factor pairs of 855 are: (1, 855), (3, 285), (5, 171), (9, 95), (15, 57), and (19, 45).</p>

27 <p>For every positive factor, there is a negative factor.</p>

63 <p>There are 9 friends and 855 candies. How will they divide them equally?</p>

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

65 <p>They will get 95 candies each.</p>

66 <h3>Explanation</h3>

67 <p>To divide the candies equally, we need to divide the total candies with the number of friends.</p>

71 <p>A rectangular garden has a length of 19 meters and a total area of 855 square meters. Find the width.</p>

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

73 <p>45 meters.</p>

74 <h3>Explanation</h3>

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

76 <p>855 = 19 × width</p>

77 <p>To find the value of width, we need to shift 19 to the left side.</p>

78 <p>855/19 = width</p>

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