Question
Find the least common multiple for 4 and 5.(1 point)
$$
The least common multiple (LCM) of two numbers is the smallest number that both numbers can divide evenly into.
To find the LCM of 4 and 5, we can list the multiples of each number until we find a common multiple:
Multiples of 4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, ...
Multiples of 5: 5, 10, 15, 20, 25, 30, 35, 40, ...
From the list, we can see that the common multiple of 4 and 5 is 20.
Therefore, the least common multiple of 4 and 5 is 20.
