Given the sets \(A = \{17, 29, 65, 1, 19\}\) and \(B = \{3, 9, 29, 101, 65\}\), what is the sum of all the elements in \(A \cap B\)?

If \[\begin{align} A &= \{x \mid x \text{ is any positive factor of } 52\} \\ B &= \{x \mid x \text{ is any positive factor of } 338\}, \end{align} \]

what is \(A \cap B?\)
