Hi, I have come across the following question: How many multiples of x or y exist within a given range?
I know we use the following formula to determine the number of multiples of x within a range using ((last multiple of x in range- first multiple of x within range)/x +1) and similar for y, but when it comes to subtracting multiples of both x and y within the range, do we just subtract them once or twice from the sum of the multiples of x and y to avoid double counting?
