Finding the Greatest Common Factor (GCF) is really useful, especially when you’re in Year 7 math and learning about factors and multiples. Here’s a simple way to do it:
List the Factors: First, write down all the factors for each number. Let’s say you’re looking at 12 and 18. You would list them like this:
Find the Common Factors: Next, find the factors that are in both lists. From the lists above, the common factors are 1, 2, 3, and 6.
Pick the Largest One: Lastly, the GCF is the biggest factor that is the same in both lists. So, for 12 and 18, the GCF is 6.
And that’s all there is to it! The more you practice, the easier it gets. So, try it out with different pairs of numbers!
