To factor the expression \(48r - 16s - 8t\), we first look for the greatest common factor (GCF) of the coefficients:
- The coefficients are 48, -16, and -8.
- The GCF of 48, 16, and 8 is 8.
Now we factor out 8 from each term:
\[ 48r - 16s - 8t = 8(6r - 2s - t) \]
Thus, the expression factored as a product with a whole number greater than 1 is:
\[ 8(6r - 2s - t) \]
