Final Answer:
The numbers to cross out (i.e., the factors that *are* factors of the center number) are:
- For 12: 1, 2, 3, 4, 6
- For 18: 1, 2, 3, 6, 9
- For 16: 1, 2, 4, 8
- For 24: 1, 2, 3, 4, 6, 8
- For 26: 1, 2, 13
- For 32: 1, 2, 4, 8, 16
- For 36: 1, 2, 3, 4, 6, 9, 12
But the task says:
“Put an × on the numbers that are *not* factors of the center number.”
So the correct answer is the list of numbers *to mark with ×*, i.e., the non-factors.
Let’s compute each circle carefully:
1. Center = 12
Surrounding numbers: 9, 1, 2, 3, 4, 5, 6, 7
Factors of 12: 1, 2, 3, 4, 6
→ Non-factors:
9, 5, 7
2. Center = 18
Numbers: 3, 1, 2, 5, 6, 7, 9, 10
Factors of 18: 1, 2, 3, 6, 9
→ Non-factors:
5, 7, 10
3. Center = 16
Numbers: 10, 1, 2, 3, 4, 5, 6, 8
Factors of 16: 1, 2, 4, 8
→ Non-factors:
10, 3, 5, 6
4. Center = 24
Numbers: 3, 1, 2, 4, 5, 6, 8, 10
Factors of 24: 1, 2, 3, 4, 6, 8
→ Non-factors:
5, 10
5. Center = 26
Numbers: 13, 1, 2, 3, 4, 5, 6, 8
Factors of 26: 1, 2, 13
→ Non-factors:
3, 4, 5, 6, 8
6. Center = 32
Numbers: 7, 1, 2, 3, 4, 5, 6, 8, 10, 16 — wait, there are 10 numbers? Let’s count from image: actually, the circle shows: 7, 4, 1, 2, 3, 5, 6, 8, 10, 16 — but standard layout has 8 numbers. Looking closely (using zoom), the circle for 32 has: 7, 4, 1, 2, 3, 5, 6, 8, 10, 16 — that’s 10, but likely only 8 are intended. From the image layout (standard worksheet), each circle has 8 numbers around.
Let me re-express based on typical version of this worksheet (known common problem):
Actually, to be precise, I need to zoom in to read each circle correctly.
