To factor the expression \( 16d - 12 \) using the greatest common factor (GCF), follow these steps:
-
Identify the GCF of the coefficients (16 and 12). The GCF of 16 and 12 is 4.
-
Factor out the GCF from the expression:
\[ 16d - 12 = 4(4d - 3) \]
Thus, the factored form of \( 16d - 12 \) is \( 4(4d - 3) \).
