Alright, let's break it down! GCF stands for Greatest Common Factor. The GCF is the largest number that can exactly divide two or more numbers. To find the GCF of fractions, we'll first need to understand how to find the GCF of whole numbers and then apply that to fractions. Here's how we do it:
Step 1: Find the prime factors of each number in the fraction.
Step 2: Identify the common prime factors of all the numbers.
Step 3: Multiply the common prime factors to get the GCF.
For example, let's find the GCF of the fractions 6/18 and 8/20:
(Step 1) First, find the prime factors of the numbers in each fraction:
6 = 2 x 3, 18 = 2 x 3 x 3, 8 = 2 x 2 x 2, 20 = 2 x 2 x 5.
(Step 2) Next, identify the common prime factors: 2 and 3.
(Step 3) Finally, multiply the common prime factors to get the GCF: 2 x 3 = 6.
So, the GCF of 6/18 and 8/20 is 6.
