The image asks you to "use your answer to Question 3 to find the HCF of 98 and 56 (use Venn diagrams)."

We can still solve for the Highest Common Factor (HCF) of 98 and 56 using Venn diagrams. Here's how:

### Step 1: Prime Factorization
- **Prime factors of 98:**
   \( 98 = 2 \times 7^2 \)
- **Prime factors of 56:**
   \( 56 = 2^3 \times 7 \)

### Step 2: Venn Diagram
- In the Venn diagram, one circle represents the factors of 98 and the other represents the factors of 56.
- The **intersection** contains the common factors. 

#### 98's factors:
- \( 2, 7, 7 \)

#### 56's factors:
- \( 2, 2, 2, 7 \)

#### Common factors:
- Both have **2** and **7** as factors.

### Step 3: Calculate HCF
- The HCF is obtained by multiplying the common prime factors in the intersection:
  \[
  HCF = 2 \times 7 = 14
  \]

The HCF of 98 and 56 is **14**.
