To factor the expression \(28w - 16x\), we first need to find the greatest common factor (GCF) of the coefficients 28 and 16.
The factors of 28 are: \(1, 2, 4, 7, 14, 28\)
The factors of 16 are: \(1, 2, 4, 8, 16\)
The greatest common factor is \(4\).
Now, we can factor out \(4\) from the expression:
\[ 28w - 16x = 4(7w - 4x) \]
Thus, the factored form is:
\[ 4(7w - 4x) \]
This is the product with a whole number greater than 1.
