Ответ:
72
Step-by-step explanation:
Consider the least common multiple of 6 and 8
The multiples of 6 are : 6, 12, 18, 24, 30, 36,
The multiples of 8 are : 8, 16, 24, 32, 40,
The common multiple is 24 or 48 or 72
The multiples of 18 are : 18, 36, 54, 72, 90,
Since 72 is a common multiple of 8 and 6 and also a multiple of 72
Then the least common multiple of 6, 18 and 8 is 72
