Page of 2 ZOOM Greatest Non-Trivial Factor Objectives: . Practice while loop. Write a function to compute the greatest non-trivial factor of a given natural number. Note that a natural number can have multiple factors; for example, 1, 2, 3, 4, 6 and 12 are all factors of 12. Factors different from 1 and the number itself are said to be non-trivial. The function should be named greatest nontrivial_factor and be able to accept a natural number as argument. It returns the greatest non-trivial factor of the passed-in number. If no greatest non-trivial factor can be found, your function should return None, a special value in Python. After function design, continue to write code to interact with users for computing the greatest non- trivial factor of a given natural number by using your defined greatest_rontrivial_Factor function. Your code shall prompt for a natural number and then display a message to report the greatest non-trivial factor of the entered number. . Function specifications: Function name o greatest_nontrivial_factor Input parameter A natural number Return value the greatest non-trivial factor of the passed-in argument (note that if the greatest non- trivial factor does not exist, the return value should be None) User interface specifications: Input The program prompts for a natural number. Output Display a message to report the greatest non-trivial factor of the entered number Testing: Develop at least 2 test cases, calculate the correct results by hand, and then confirm that your program gives the same results. You do not need to submit your test cases. . . . of 2 ZOOM Page
