To factor the linear expression \(30d + 24\) using the greatest common factor (GCF), first, we need to determine the GCF of the coefficients \(30\) and \(24\).
-
Find the GCF of 30 and 24:
- The factors of \(30\) are: \(1, 2, 3, 5, 6, 10, 15, 30\)
- The factors of \(24\) are: \(1, 2, 3, 4, 6, 8, 12, 24\)
- The common factors are: \(1, 2, 3, 6\)
- The greatest common factor is \(6\).
-
Factor out the GCF:
- Divide each term in the expression by the GCF:
- \(30d \div 6 = 5d\)
- \(24 \div 6 = 4\)
-
Write the factored expression: \[ 30d + 24 = 6(5d + 4) \]
Thus, the factored form of \(30d + 24\) using the GCF is: \[ 6(5d + 4) \]
