To find the greatest common factor (GCF) of the expression \(9w - 24\), we can factor out the common factor from the two terms.
The terms are \(9w\) and \(-24\).
- The coefficient of \(9w\) is 9.
- The constant term is -24.
Next, we need to find the GCF of the numerical coefficients 9 and 24.
- The factors of 9 are: 1, 3, 9
- The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, 24
The common factors of 9 and 24 are: 1 and 3.
The greatest of these common factors is 3.
Therefore, the GCF of \(9w - 24\) is \(3\).
So the answer is 3.
