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