    Given the total number of vehicles passing through an intersection during a specific time interval, calculate the sum of all possible time slot durations (divisors) that could evenly accommodate the traffic flow for optimal traffic light timing. The resulting sum will help determine the most efficient traffic light cycle length that can handle the observed vehicle count while maintaining smooth traffic flow.
