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 to schedule events. In this topic, we will learn about the GCF of 3 and 48.</p>

4 <h2>What is the GCF of 3 and 48?</h2>

5 <p>The<a>greatest common factor</a>of 3 and 48 is 3. The largest<a>divisor</a>of two or more<a>numbers</a>is called the GCF of the numbers.</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 3 and 48?</h2>

8 <p>To find the GCF of 3 and 48, a few methods are described below:</p>

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

10 <li>Prime Factorization </li>

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

12 </ul><h3>GCF of 3 and 48 by Using Listing of Factors</h3>

13 <p>Steps to find the GCF of 3 and 48 using the listing of<a>factors</a>:</p>

14 <p><strong>Step 1:</strong>Firstly, list the factors of each number Factors of 3 = 1, 3. Factors of 48 = 1, 2, 3, 4, 6, 8, 12, 16, 24, 48.</p>
