Due to its common embryonic origin and its innervation and action.
The adductor muscles of the hip are four in number: the adductor brevis, the adductor longus, the adductor magnus and the adductor minimus. All the hip adductors originate from the pubis and insert at the medial side of the femur.
There is the adductor magnus, adductor brevis, adductor longus and gracilis, so there are at least 4.
The medial compartment of the thigh includes the hamstring portion of the adductor magnus. This muscle is innervated by the sciatica.
The abductor magnus does not exist. It is likely a mistake referring to the aDDuctor magnus.

The knee. The prime mover for extension of the knee joint is the quadraceps femoris which is actually a group of muscles consisting of rectus femoris, vastus lateralis, vastus medialis and vastus intermedialis. Extension here is assisted by hamstring part of the adductor magnus and to some extent by the adductor brevis.

Adductor magnus
The gastrocnemius muscle originates from the adductor Magnus at the top of the frog's leg. The adductor Magnus splits off into the gracilus minor to the rear, and gracilus major to the front. These connect in the gastrocnemius.
