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

4 <h2>What are the Factors of 649?</h2>

5 <p>The<a>numbers</a>that divide 649 evenly are known as<a>factors</a><a>of</a>649. A factor of 649 is a number that divides the number without<a>remainder</a>. The factors of 649 are 1, 17, 38, and 649.</p>

6 <p><strong>Negative factors of 649:</strong>-1, -17, -38, and -649.</p>

7 <p><strong>Prime factors of 649:</strong>17 and 38.</p>

8 <p><strong>Prime factorization of 649:</strong>17 × 38.</p>

9 <p><strong>The<a>sum</a>of factors of 649:</strong>1 + 17 + 38 + 649 = 705</p>

10 <h2>How to Find Factors of 649?</h2>

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

12 <ol><li>Finding factors using<a>multiplication</a></li>

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

14 <li>Prime factors and Prime factorization</li>

15 </ol><h2>Finding Factors Using Multiplication</h2>

16 <p>To find factors using multiplication, we need to identify the pairs of numbers that are multiplied to give 649. Identifying the numbers which are multiplied to get the number 649 is the multiplication method.</p>

17 <p><strong>Step 1:</strong>Multiply 649 by 1, 649 × 1 = 649.</p>

18 <p><strong>Step 2:</strong>Check for other numbers that give 649 after multiplying 17 × 38 = 649</p>

19 <p>Therefore, the positive factor pairs of 649 are: (1, 649) and (17, 38). All these factor pairs result in 649. For every positive factor, there is a negative factor.</p>

47 <h3>Problem 1</h3>

48 <p>There are 17 students and 649 pages of a book. How will they divide it equally?</p>

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

50 <p>They will get 38 pages each.</p>

51 <h3>Explanation</h3>

52 <p>To divide the pages equally, we need to divide the total pages with the number of students.</p>

53 <p>649/17 = 38</p>

54 <p>Well explained 👍</p>

55 <h3>Problem 2</h3>

56 <p>A garden is rectangular, the length of the garden is 38 meters and the total area is 649 square meters. Find the width?</p>

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

58 <p>17 meters.</p>

59 <h3>Explanation</h3>

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

61 <p>Area = length × width</p>

62 <p>649 = 38 × width</p>

63 <p>To find the value of width, we need to shift 38 to the left side.</p>

64 <p>649/38 = width</p>

65 <p>Width = 17.</p>
