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 explore the concept of finding the GCF for decimal numbers, specifically 13.7 and 4.9.</p>

4 <h2>What is the GCF of 13.7 and 4.9?</h2>

5 <p>The<a>greatest common factor</a>(GCF) of 13.7 and 4.9 is 0.1.</p>

6 <p>The GCF is the largest<a>number</a>that can exactly divide two or more numbers.</p>

7 <p>When dealing with<a>decimal numbers</a>, factors can also be decimal values.</p>

8 <p>The GCF of two numbers cannot be negative, as divisors are always positive.</p>

69 <p>GCF × LCM = product of the numbers</p>

71 <p>0.1 × 67.13 = 13.7 × b</p>

70 <p>0.1 × 67.13 = 13.7 × b</p>

72 <p>6.713 = 13.7b</p>
