3 <p>A number which divides another number exactly without leaving any remainder is called a factor of the given number. Factors play an important role in many real-life situations. They are useful in deciding the best time to schedule work shifts and events.</p>

4 <h2>What are the Factors of 9?</h2>

5 <p>Factors often come in pairs. There are several methods to figure them out, which you'll be learning about in a second. For now, let's just focus on the<a>factors</a><a>of</a>9, which are mentioned below:</p>

6 <p><strong>Negative factors of 9:</strong>-1, -3, -9<strong>Prime factors of 9:</strong> 3<strong>Prime factorization of 9: </strong>32<strong>The<a>sum</a>of factors of 9:</strong> 1 + 3 + 9 = 13 </p>

7 <h2>How to Find the Factors of 9?</h2>

8 <p>For finding factors, school kids use different methods for easy calculation. A few commonly used methods are as follows:</p>

9 <ul><li>Use of Multiplication Method</li>

10 <li>Use of Division Method</li>

11 <li>Use of Prime Factors and Prime Factorization.</li>

12 </ul><p>So, here we discuss a detailed explanation of the following methods: </p>

13 <h3>Finding Factors Using Multiplication Method</h3>

14 <p> In the<a>multiplication</a>method, we will try to find out what<a>numbers</a>will multiply together, and give us the value 9. We will check the factors step by step:</p>

15 <p><strong>Step 1:</strong>Start to multiply with numbers, which gives the value of 9.</p>

16 <p>Start with 1, and continue to multiply with other numbers. </p>

17 <p>1 × 9 = 9 3 × 3 = 9</p>

18 <p><strong>Step 2:</strong>After the calculation, we get these numbers, the factors of 9.</p>

19 <p><strong>Step 3:</strong>The positive factor pairs of 9 found through multiplication are (1,9) and (3,3)</p>

20 <p><strong>Step 4:</strong>The negative factor pairs of 9 are (-1,-9), and (-3,-3) </p>

23 <p>Using this method we will break down the given number till our<a>remainder</a>is zero. Let us go through the step-by-step process to find the factors of 9:</p>

25 <p><strong>Step 1:</strong>Divide 9 by smaller numbers and see if there is any remainder. E.g., 9/1 = 9. </p>

24 <p><strong>Step 1:</strong>Divide 9 by smaller numbers and see if there is any remainder. E.g., 9/1 = 9. </p>

26 <p><strong>Step 2:</strong>We will continue in the same way and check for other numbers as well. For 9, the factors are 1, 3, and 9. Because 9 can be divided evenly by these numbers. </p>
