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 -225, how they are used in real life, and tips to learn them quickly.</p>

4 <h2>What are the Factors of -225?</h2>

5 <p>The<a>numbers</a>that divide -225 evenly are known as<a>factors</a><a>of</a>-225.</p>

6 <p>A factor of -225 is a number that divides the number without<a>remainder</a>.</p>

7 <p>The factors of -225 are 1, 3, 5, 9, 15, 25, 45, 75, and 225.</p>

8 <p>Negative factors of -225: -1, -3, -5, -9, -15, -25, -45, -75, and -225. Prime factors of -225: 3 and 5.</p>

9 <p>Prime factorization of -225: -1 × 3² × 5².</p>

10 <p>The<a>sum</a>of the positive factors of 225: 1 + 3 + 5 + 9 + 15 + 25 + 45 + 75 + 225 = 403</p>

11 <h2>How to Find Factors of -225?</h2>

12 <p>Factors can be found using different methods. Mentioned below are some commonly used methods:</p>

13 <ul><li>Finding factors using<a>multiplication</a> </li>

14 <li>Finding factors using<a>division</a>method </li>

15 <li>Prime factors and<a>prime factorization</a></li>

16 </ul><h3>Finding Factors Using Multiplication</h3>

17 <p>To find factors using multiplication, we need to identify the pairs of numbers that are multiplied to give -225. Identifying the numbers which are multiplied to get the number -225 is the multiplication method.</p>

18 <p><strong>Step 1:</strong>Multiply -225 by 1, -225 × 1 = -225.</p>

19 <p><strong>Step 2:</strong>Check for other numbers that give -225 after multiplying</p>

20 <p>3 × -75 = -225</p>

21 <p>5 × -45 = -225</p>

22 <p>9 × -25 = -225</p>

23 <p>15 × -15 = -225</p>

24 <p>Therefore, the positive factor pairs of -225 are: (1, -225), (3, -75), (5, -45), (9, -25), (15, -15).</p>

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

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

73 <p>Area = length × width</p>

72 <p>Area = length × width</p>

74 <p>225 = 9 × width</p>

73 <p>225 = 9 × width</p>

75 <p>To find the value of width, we need to shift 9 to the left side.</p>
