    Design a fraud detection function that calculates the sum of all possible transaction split patterns for a given credit card charge amount, where each split represents a potential fraudulent sub-transaction. The function should analyze a primary transaction amount and return the sum of all its possible divisor values, which could indicate structured fraud attempts through multiple smaller charges.
