The least common multiple of a set of integers is the smallest positive integer divisible by all integers in the set.

The prime factorization of $12$ is $2^{2} \times 3$.

The prime factorization of $24$ is $2^{3} \times 3$.

The prime factorization of $40$ is $2^{3} \times 5$.

Find the least common multiple by multiplying the prime number powers together, including only the greatest prime number power of each common prime.

$\text{lcm}(12, 24, 40) = 2 \times 3 \times 5 = 120.$
