You are to create a class Multiples with a method number, which takes three ints: min, max, and factor.
Given a range of integers from min to max (inclusive), determine how many numbers within that range are evenly divisible by factor.
|-||If x is evenly divisble by y, there exists some integer k such that k * y = x.|
|-||min will be between -1000000 and 1000000, inclusive.|
|-||max will be between -1000000 and 1000000, inclusive.|
|-||max will be greater than or equal to min.|
|-||factor will be between 1 and 1000, inclusive.|
