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: [[-130, -20, -171, -122, 49, -43], [-173, -82, 17], [87, -55, -70, -113], [69, 10, -121, -177]]
Example Output: [49, 17, 87, 69]

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: [[20, -151, -171, -144, -120], [60, 47], [-141, -164, 26, 56, -140, 46, -15]]
Example Output:
[20, 60, 56]
