Groups. All orders divides order of maximal element

Order: divides order of maximal element

Let G be a [something] group, and let g∈G be an element with maximal finite order. Any other element with finite order has an order that [has what relationship?].

The same statement cannot be made for non-comutative groups.

Can you remember the proof?

Maximal finite order

Let g be an element of group G. g has maximal finite order iff all other elements with finite order have an order less than that of g.
