The greatest common factor (GCF) of 16, 8, and 12 is 4.
To find the GCF, we start by identifying the factors of each number:
- Factors of 16 are: 1, 2, 4, 8, 16
- Factors of 8 are: 1, 2, 4, 8
- Factors of 12 are: 1, 2, 3, 4, 6, 12
Next, we look for the common factors among these lists:
- Common factors of 16, 8, and 12 are: 1, 2, 4
Among these, the greatest factor is 4. Therefore, the greatest common factor of 16, 8, and 12 is 4.
