To factor the expression \(5p + 15\), we can look for the greatest common factor (GCF) of the terms.
The GCF of \(5p\) and \(15\) is \(5\).
Now, we can factor out \(5\):
\[ 5p + 15 = 5(p + 3) \]
Thus, the factored form of \(5p + 15\) is:
\[ 5(p + 3) \]
This is a product with a whole number greater than 1, which is \(5\).
