Answer

15

Work Step by Step

The least common multiple is the smallest positive number that is a multiple of two or more numbers. The two numbers in the question are 5 and 15. 5 is a multiple of 15, and 15 is already the first multiple of 15 (15 times 1 = 15). This is why the least common multiple of these two numbers is 15.
