3 <p>In mathematics, there are lots of numbers that when divided by other numbers leave no remainder, these numbers are called factors. We use it in our vehicles mileage and money handling. Now, we’ll learn what factors are and factors of 225 let us now see.</p>

4 <h2>Factors Of 225</h2>

5 <p>We can tell if a<a>number</a>has more than 2<a>factors</a>just by seeing if a number is a<a>prime number</a>or not. As none of the<a>even numbers</a>except 2 are prime numbers, we can tell that 225 has more than 2 factors. Let us find what the factors are.</p>

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

7 <p><strong>Prime factors of 225:</strong>The<a>prime factors</a>of 225 are 3 and 5.</p>

8 <p><strong>Prime factorization of 225:</strong>5×5×3×3.</p>

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

10 <h2>How to find the factors of 225</h2>

11 <p>Children use<a>multiple</a>ways to find factors of a number. Let us look at some ways we can use to find the factors of 225.</p>

12 <ul><li>Multiplication Method</li>

13 </ul><ul><li>Division Method</li>

15 </ul><h3>Finding The Factors Of 225 Using Multiplication</h3>

16 <p>In the<a>multiplication</a>method, we find pairs of numbers where the<a>product</a>will be 225. In this process, possible steps will be - </p>

17 <p><strong>Step 1:</strong>Find all those numbers whose product will be 225.</p>

18 <p><strong>Step 2:</strong>These numbers will be called the factors of 225.</p>

19 <p><strong>Step 3:</strong>Students have to write these pairs of numbers for this method.</p>

20 <p>List of numbers whose product is 225</p>

21 <p>225×1= 225</p>

22 <p>75×3= 225</p>

23 <p>45×5= 225</p>

24 <p>25×9= 225</p>

25 <p>15×15= 225</p>

26 <p>So the pair of numbers whose product is 225 are (1,225), (3,75), (5,45), (9,25) and (15,15). </p>
