In this task, you are given a list. This list contains many lists of integers. The list is several items written within a []. Your task is to find the maximum number among the members of each inner list. The output should be a list comprised of the maximums with the same order as the internal lists.

[[-152, -12], [10, -52], [-104, 77], [73, -72, 72]]
[-12, 10, 77, 73]

[[-169, -104, 48, -186, 57, -108], [-36, 65, -62, -91, 58, 55, -136], [-107, -18], [-52, -153, 45, -119, -105, 18], [65, 58, -15, -79, 82, -93], [-178, 96, -64], [44, -116, -197, -109, -15], [-161, 23, -115, -148, -175, -189, -175]]
[57, 65, -18, 45, 82, 96, 44, 23]

[[61, 91, -109, -50, -79], [-189, 10, 56, 1]]

[91, 56]
