$7 {u}^{5} v$

#### Explanation:

The GCF means, "what is the most that all the terms have in common?" ie "What do they ALL share?

You should notice that $28 , 35 \mathmr{and} 49$ are all multiples of $7$

The terms also each contain ${u}^{5}$. Some have more than this, but there is ${u}^{5}$ in all of them.

In the same way they all have $v$

The GCF is therefore: $7 {u}^{5} v$
