3 <p>The GCF is the largest number that can divide two or more numbers without leaving any remainder. GCF is used to share the items equally, to group or arrange items, and schedule events. In this topic, we will learn about the GCF of 35 and 65.</p>

4 <h2>What is the GCF of 35 and 65?</h2>

5 <p>The<a>greatest common factor</a><a>of</a>35 and 65 is 5. The largest<a>divisor</a>of two or more<a>numbers</a>is called the GCF of the number.</p>

6 <p>If two numbers are co-prime, they have no common factors other than 1, so their GCF is 1.</p>

7 <p>The GCF of two numbers cannot be negative because divisors are always positive.</p>

8 <h2>How to find the GCF of 35 and 65?</h2>

9 <p>To find the GCF of 35 and 65, a few methods are described below:</p>

10 <ol><li>Listing Factors</li>

11 <li>Prime Factorization</li>

12 <li>Long Division Method / by Euclidean Algorithm</li>

13 </ol><h2>GCF of 35 and 65 by Using Listing of Factors</h2>

14 <p>Steps to find the GCF of 35 and 65 using the listing of<a>factors</a>:</p>

15 <p><strong>Step 1:</strong>Firstly, list the factors of each number.</p>

16 <p>Factors of 35 = 1, 5, 7, 35.</p>

17 <p>Factors of 65 = 1, 5, 13, 65.</p>

30 <p>Find the GCF of 35 and 65 using the<a>division</a>method or Euclidean Algorithm Method. Follow these steps:</p>

32 <p><strong>Step 1:</strong>First, divide the larger number by the smaller number.</p>

31 <p><strong>Step 1:</strong>First, divide the larger number by the smaller number.</p>

33 <p>Here, divide 65 by 35. 65 ÷ 35 = 1 (<a>quotient</a>), The<a>remainder</a>is calculated as 65 - (35×1) = 30.</p>

32 <p>Here, divide 65 by 35. 65 ÷ 35 = 1 (<a>quotient</a>), The<a>remainder</a>is calculated as 65 - (35×1) = 30.</p>

34 <p>The remainder is 30, not zero, so continue the process.</p>

33 <p>The remainder is 30, not zero, so continue the process.</p>

35 <p><strong>Step 2:</strong>Now divide the previous divisor (35) by the previous remainder (30). 35 ÷ 30 = 1 (quotient), remainder = 35 - (30×1) = 5.</p>

34 <p><strong>Step 2:</strong>Now divide the previous divisor (35) by the previous remainder (30). 35 ÷ 30 = 1 (quotient), remainder = 35 - (30×1) = 5.</p>

36 <p><strong>Step 3:</strong>Now divide the previous divisor (30) by the previous remainder (5). 30 ÷ 5 = 6 (quotient), remainder = 30 - (5×6) = 0.</p>

35 <p><strong>Step 3:</strong>Now divide the previous divisor (30) by the previous remainder (5). 30 ÷ 5 = 6 (quotient), remainder = 30 - (5×6) = 0.</p>

37 <p>The remainder is zero, the divisor will become the GCF. The GCF of 35 and 65 is 5.</p>
