What is the sum of the first two positive integers which satisfy \(n' = n\), where \(n'\) is the arithmetic derivative of \(n\)?

**Clarification:** The arithmetic derivative of \(n\) is given by:

- \( n' = 0\) for \(n\) = 1 or 0.
- \(n' = 1\) if is prime.
- \(n' = a'b + b'a\) if \(n\) is composite, where \(a\) and \(b\) are factors of \(n\)
