Add New: Divisor and multiple.
Divisor and multiple:
All numbers are added to two queues alternately. Two groups of numbers are compared in turn and divided by their greatest common divisor. If the quotient is 1, the number will be eliminated, otherwise the quotient will be retained. The remaining numbers continue to operate in order until all the numbers in the queue are eliminated or the two quotients are not 1, then the operation stops. The goal is to eliminate all the numbers. How to Play: (1) Click the number on the board to add to the current queue. (2) Click the number in the current queue, then click the number on the board to replace the number in the queue. (3) Click the HINT button to display the ratio of the product of the numbers in each queue.
