3 <p>The GCF, or greatest common factor, 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 14 and 49.</p>

4 <h2>What is the GCF of 14 and 49?</h2>

5 <p>The<a>greatest common factor</a>of 14 and 49 is 7. The largest<a>divisor</a>of two or more<a>numbers</a>is called the GCF of those numbers. 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>
