One limit of this table: it lists only Micro Four Thirds lenses that mount natively on the Olympus OM-D E-M10 IV — lenses fitted through an adapter are not included here. See which mounts adapt to which.

What these focal lengths actually give you on the Olympus OM-D E-M10 IV

The Olympus OM-D E-M10 IV has a Micro Four Thirds sensor, so it sees a 2× crop of what each lens projects. Every focal length below therefore frames 2× tighter than its marked number. That works in your favour here: the OM System M.Zuiko 150-600mm f/5-6.3 IS reaches 1200mm of effective reach, which on a full-frame body would need a longer, heavier and far more expensive lens.

Effective focal lengths are the marked focal length × the 2× sensor crop factor — the field of view, not a change in the lens itself. Aperture and depth of field are unaffected.
