To find the least common multiple (LCM) of 15, 12, and 10, we can list their multiples:
Multiples of 15: 15, 30, 45, 60, ...
Multiples of 12: 12, 24, 36, 48, 60, ...
Multiples of 10: 10, 20, 30, 40, 50, 60, ...
The first time all three numbers appear in the list is 60. Therefore, the baker will first remove the scones, muffins, and cookies at the same time after 60 minutes.
