Final answer:
The lowest common multiple (LCM) of 4, 6, and 8 is 24. It is the smallest number that is a multiple of all three given numbers.
Step-by-step explanation:
The lowest common multiple (LCM) of 4, 6, and 8 can be found by listing the multiples of each number and finding the smallest number that appears in all lists. For number 4, the multiples are 4, 8, 12, 16, 20, and so on. For number 6, the multiples are 6, 12, 18, 24, and so on. For number 8, the multiples are 8, 16, 24, and so on. Looking through these lists, the smallest number that all three lists have in common is 24. Therefore, the LCM of 4, 6, and 8 is 24.
