Would you like more detailed explanations or have any questions?

Here are 5 questions to expand on the topic:
1. How do you find the GCF of two numbers using prime factorization?
2. Can you find the least common multiple (LCM) of two numbers instead of the GCF?
3. What is the relationship between the GCF and LCM of two numbers?
4. How can you use the Euclidean algorithm to find the GCF of larger numbers?
5. How does the GCF apply to real-world problems, such as dividing things into equal parts?

**Tip:** When finding the GCF, start by identifying the factors of both numbers, then look for the largest factor that they have in common.
