3 <p>The GCF is the largest number that can divide two or more numbers without leaving any remainder. GCF is used to share items equally, group or arrange items, and schedule events. In this topic, we will learn about the GCF of 25 and 60.</p>

4 <h2>What is the GCF of 25 and 60?</h2>

5 <p>The<a>greatest common factor</a>of 25 and 60 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. The GCF of two numbers cannot be negative because divisors are always positive.</p>

7 <h2>How to find the GCF of 25 and 60?</h2>

8 <p>To find the GCF of 25 and 60, a few methods are described below </p>

9 <ul><li>Listing Factors </li>

10 <li>Prime Factorization </li>

11 <li>Long Division Method / Euclidean Algorithm</li>

12 </ul><h2>GCF of 25 and 60 by Using Listing of Factors</h2>

13 <p>Steps to find the GCF of 25 and 60 using the listing of<a>factors</a></p>

14 <p><strong>Step 1:</strong>Firstly, list the factors of each number Factors of 25 = 1, 5, 25. Factors of 60 = 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60.</p>

15 <p><strong>Step 2:</strong>Now, identify the<a>common factors</a>of them Common factors of 25 and 60: 1, 5.</p>

16 <p><strong>Step 3:</strong>Choose the largest factor The largest factor that both numbers have is 5. The GCF of 25 and 60 is 5.</p>

24 <p>Find the GCF of 25 and 60 using the<a>division</a>method or Euclidean Algorithm Method. Follow these steps:</p>

26 <p><strong>Step 1:</strong>First, divide the larger number by the smaller number Here, divide 60 by 25 60 ÷ 25 = 2 (<a>quotient</a>), The<a>remainder</a>is calculated as 60 - (25×2) = 10 The remainder is 10, not zero, so continue the process</p>

25 <p><strong>Step 1:</strong>First, divide the larger number by the smaller number Here, divide 60 by 25 60 ÷ 25 = 2 (<a>quotient</a>), The<a>remainder</a>is calculated as 60 - (25×2) = 10 The remainder is 10, not zero, so continue the process</p>

27 <p><strong>Step 2:</strong>Now divide the previous divisor (25) by the previous remainder (10) Divide 25 by 10 25 ÷ 10 = 2 (quotient), remainder = 25 - (10×2) = 5</p>

26 <p><strong>Step 2:</strong>Now divide the previous divisor (25) by the previous remainder (10) Divide 25 by 10 25 ÷ 10 = 2 (quotient), remainder = 25 - (10×2) = 5</p>

28 <p><strong>Step 3:</strong>Now divide the previous divisor (10) by the previous remainder (5) Divide 10 by 5 10 ÷ 5 = 2 (quotient), remainder = 10 - (5×2) = 0 The remainder is zero, the divisor will become the GCF. The GCF of 25 and 60 is 5.</p>

27 <p><strong>Step 3:</strong>Now divide the previous divisor (10) by the previous remainder (5) Divide 10 by 5 10 ÷ 5 = 2 (quotient), remainder = 10 - (5×2) = 0 The remainder is zero, the divisor will become the GCF. The GCF of 25 and 60 is 5.</p>
