Definition: Multiplicative Functions
An arithmetic function \(\beta\) with at least one \(m\in\mathbb N\) with \(\beta(m)\neq 0\) is called:
 multiplicative, \(\beta(mn)=\beta(m)\beta(n)\) for all relatively prime \(m,n\in\mathbb N\),
 multiplicative, \(\beta(mn)=\beta(m)\beta(n)\) for all relatively prime \(m,n\in\mathbb N\),
