📄 What I Can See:
You’ve shared a math worksheet titled:
>
“Math Worksheet: Greatest Common Factor”
It includes 10 numbered problems asking for the GCF (Greatest Common Factor) of pairs of numbers. For example:
1. 6, 4
2. 2, 8
3. 8, 2
... etc.
At the bottom, it says:
> “Solve each problem. Answer key is on the back side.”
And there’s a QR code and logo for “Math-Aids.com”.

✔ Let’s Solve All 10 Problems Together
We’ll find the
GCF (also called
GCD, Greatest Common Divisor) of each pair using prime factorization or listing factors.
---
🔢 Problem 1: GCF of 6 and 4
- Factors of 6: 1, 2, 3, 6
- Factors of 4: 1, 2, 4
→
Common: 1, 2 → GCF = 2
✔ Answer: 2
---
🔢 Problem 2: GCF of 2 and 8
- Factors of 2: 1, 2
- Factors of 8: 1, 2, 4, 8
→
Common: 1, 2 → GCF = 2
✔ Answer: 2
---
🔢 Problem 3: GCF of 8 and 2
Same as above — order doesn’t matter.
✔ Answer: 2
---
🔢 Problem 4: GCF of 4 and 7
- Factors of 4: 1, 2, 4
- Factors of 7: 1, 7
→ Only common factor:
1
✔ Answer: 1
---
🔢 Problem 5: GCF of 6 and 7
- Factors of 6: 1, 2, 3, 6
- Factors of 7: 1, 7
→ Only common:
1
✔ Answer: 1
---
🔢 Problem 6: GCF of 12 and 27
- Factors of 12: 1, 2, 3, 4, 6, 12
- Factors of 27: 1, 3, 9, 27
→ Common: 1, 3 →
GCF = 3
✔ Answer: 3
---
🔢 Problem 7: GCF of 4 and 8
- Factors of 4: 1, 2, 4
- Factors of 8: 1, 2, 4, 8
→ Common: 1, 2, 4 →
GCF = 4
✔ Answer: 4
---
🔢 Problem 8: GCF of 16 and 24
- Factors of 16: 1, 2, 4, 8, 16
- Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24
→ Common: 1, 2, 4, 8 →
GCF = 8
✔ Answer: 8
---
🔢 Problem 9: GCF of 18 and 36
- 36 is a multiple of 18 → so GCF is
18
✔ Answer: 18
---
🔢 Problem 10: GCF of 12 and 30
- Factors of 12: 1, 2, 3, 4, 6, 12
- Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30
→ Common: 1, 2, 3, 6 →
GCF = 6
✔ Answer: 6

## 💡 Tip: How to Find GCF Quickly
-
List factors of both numbers → pick the largest common one.
- Or use
prime factorization:
- Example: GCF(12, 30)
- 12 = 2² × 3
- 30 = 2 × 3 × 5
- Take lowest powers of common primes → 2¹ × 3¹ =
