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 the<a>numbers</a>that multiply together to give the value, 42, 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 42.</p>

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

17 <p>1 × 42 = 42 2 × 21 = 42 3 × 14 = 42 6 × 7 = 42</p>

18 <p><strong>Step 2</strong>: After the calculation, we get to these numbers, the factors of 42.</p>

19 <p><strong>Step 3:</strong>The positive factor pairs of 42 found through multiplication are (1, 42), (2, 21), (3, 14), and (6, 7)</p>

20 <p><strong>Step 4:</strong>The negative factor pairs of 274 are (-1, -42), (-2, -21), (-3, -14), and (-6, -7) </p>
