The Greatest Common Factor (GCF) of 12, 18, and 36 is 6.
To find the GCF, we can list the factors of each number:
- Factors of 12: 1, 2, 3, 4, 6, 12
- Factors of 18: 1, 2, 3, 6, 9, 18
- Factors of 36: 1, 2, 3, 4, 6, 9, 12, 18, 36
The common factors of 12, 18, and 36 are 1, 2, 3, and 6. The greatest of these is 6, so the GCF is 6.
