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 GCF of \(16\) and \(12\) is \(4\).
Now, we can factor out the GCF from the expression:
\[ 16d - 12 = 4(4d - 3) \]
So, the factored form of \(16d - 12\) is:
\[ 4(4d - 3) \]
