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.

Example Input: [[10, -121, -54, -1, -69, -181], [83, -37, -173, -81, -42], [-117, 86, -6, -54, -21], [-171, 22, -69]]
Example Output: [10, 83, 86, 22]

Example Input: [[-194, -52, 35, -70], [-101, -197]]
Example Output: [35, -101]

Example Input: [[-15, -101, 88, 59, 10, 21, -177], [-13, 58, 39, -149], [-196, -190, -168, -130, -147, -20, -83]]
Example Output:
[88, 58, -20]
