Read the structure
番 is a verbal measure word counting a round or spell of an extended, often deliberate action, as in 讨论一番 or 调查一番. It follows the verb and its number in the order verb + number + 番. The number and measure word cannot be reversed or moved before the verb. Keep the model Verb + Number + 番 visible while you compare each sentence.
大家认真讨论了一番。
Everyone had a serious round of discussion.
Choose the right context
Count one round of discussion or investigation. Present an action as an extended episode rather than an instant. Use 一番 after verbs that naturally support sustained effort.
警方对现场调查了一番。
The police investigated the scene thoroughly for a while.
Respect the boundary
Do not use 番 as a general noun classifier. Do not reverse 一番 to 番一. Do not place the verbal measure phrase before its verb.
大家讨论了番一。
(Everyone discussed round one.)
Repair the pattern
The number and verbal measure word are reversed: The quantity order is number + verbal measure word: 一番, not 番一. The aspect marker splits the quantity phrase: 一番 is one number-measure phrase; 了 belongs after the verb and cannot split it.
大家讨论了一番。
Use the repaired structure without changing the intended meaning.
