A recent programming challenge asked you to solve the following problem:
Find the smallest prime fibonacci number greater than a given input number. Add one to that fibonacci prime, find the factors of the result, and return the sum of the factors. For instance, if the input number is 10, the smallest fibonacci prime greater than 10 is 13, the factors of 13 + 1 = 14 are 2 and 7, and their sum is 9.
Your task is to write a function to solve that problem, then apply your function to the input number 227000. When you are finished, you are welcome to read or run a suggested solution, or to post your own solution or discuss the exercise in the comments below.
