To factor the expression \(16D - 12\) using the greatest common factor (GCF), we first need to find the GCF of the coefficients 16 and 12.
- The factors of 16 are: \(1, 2, 4, 8, 16\)
- The factors of 12 are: \(1, 2, 3, 4, 6, 12\)
The greatest common factor is \(4\).
Next, we can factor \(4\) out of the expression:
\[ 16D - 12 = 4(4D - 3) \]
Thus, the factored form of the expression \(16D - 12\) is:
\[ 4(4D - 3) \]
