To factor the expression \(2z + 6\), we can look for the greatest common factor (GCF) of the terms.
The GCF of \(2z\) and \(6\) is \(2\).
Now, we can factor out \(2\) from the expression:
\[ 2z + 6 = 2(z + 3) \]
So, the factored form of \(2z + 6\) is:
\[ 2(z + 3) \]
This answer includes the whole number \(2\), which is greater than \(1\).
