We need to find the lowest common multiple of 8 and 12.
Reminder that the LCM is the lowest number that divides evenly with both of the given numbers.
We can make a chart and see that:
Multiples of 8: 8, 16, 24, 32
Multiples of 12: 12, 24...wait! We have a match with 24!
Therefore, there will be 24 more games until both events will occur.
