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

4 <h2>What are the Factors of 987?</h2>

5 <p>The<a>numbers</a>that divide 987 evenly are known as<a>factors</a><a>of</a>987.</p>

6 <p>A factor of 987 is a number that divides the number without<a>remainder</a>.</p>

7 <p>The factors of 987 are 1, 3, 7, 21, 47, 141, 329, and 987.</p>

8 <p><strong>Negative factors of 987:</strong>-1, -3, -7, -21, -47, -141, -329, and -987.</p>

9 <p><strong>Prime factors of 987:</strong>3, 7, and 47.</p>

10 <p><strong>Prime factorization of 987:</strong>3 × 7 × 47.</p>

11 <p>The<a>sum</a>of factors of 987: 1 + 3 + 7 + 21 + 47 + 141 + 329 + 987 = 1536</p>

12 <h2>How to Find Factors of 987?</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 987. Identifying the numbers which are multiplied to get the number 987 is the multiplication method.</p>

19 <p><strong>Step 1:</strong>Multiply 987 by 1, 987 × 1 = 987.</p>

20 <p><strong>Step 2:</strong>Check for other numbers that give 987 after multiplying</p>

21 <p>3 × 329 = 987</p>

22 <p>7 × 141 = 987</p>

23 <p>21 × 47 = 987</p>

24 <p>Therefore, the positive factor pairs of 987 are: (1, 987), (3, 329), (7, 141), (21, 47).</p>

25 <p>All these factor pairs result in 987.</p>

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