To factor the expression \( 16r + 8s \), we look for the greatest common factor (GCF) of the two terms.
The terms are:
- \( 16r \)
- \( 8s \)
The GCF of 16 and 8 is 8. We can factor out 8 from both terms:
\[ 16r + 8s = 8(2r + s) \]
So, the factored expression is:
\[ 8(2r + s) \]
This is in the form of a product with a whole number greater than 1.
