Greatest Common Factor (GCF) Worksheets - Free Printable

It looks like you've uploaded an image of a worksheet titled "Greatest Common Factor", which asks students to find the greatest common factor (GCF) for each pair of numbers. Since I can't view images directly, I’ll need you to provide the actual numbers or describe the problems listed in the worksheet.

However, based on the structure of such worksheets, here’s how you solve these types of problems:

---

🔍 What is the Greatest Common Factor (GCF)?

The GCF of two numbers is the largest positive integer that divides both numbers without leaving a remainder.

---

✔ Steps to Find the GCF:

1. List the factors of each number.
2. Identify the common factors.
3. Choose the greatest one.

Alternatively, use the prime factorization method:
- Break down each number into prime factors.
- Multiply the common prime factors.

Or use the Euclidean Algorithm (for larger numbers).

📌 Example Problem (Typical from this Worksheet):

Let’s say one problem is:
Find the GCF of 12 and 18.

#### Step-by-step:
- Factors of 12: 1, 2, 3, 4, 6, 12
- Factors of 18: 1, 2, 3, 6, 9, 18
- Common factors: 1, 2, 3, 6
- GCF = 6

Now, please type out the specific pairs of numbers from your worksheet (e.g., "12 and 18", "24 and 36", etc.), and I’ll help you solve each one step by step with explanations.

Alternatively, if you can describe the image content or list the problems, I’ll be happy to assist!
