To find the least common multiple (LCM) of 3 and 5, we need to list the multiples of each number and find the lowest multiple they have in common.
Multiples of 3: 3, 6, 9, 12, 15, ...
Multiples of 5: 5, 10, 15, 20, 25, ...
From the above multiples, we see that the least common multiple of 3 and 5 is 15.
Find the least common multiple of 3 and 5.
