You asked:

Find the least common multiple of the following numbers: \(5, 20, 2\).

MathBot Answer:

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 $5$ is $5$.

The prime factorization of $20$ is $2^{2} \times 5$.

The prime factorization of $2$ is $2$.

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

$\text{lcm}(5, 20, 2) = 2^{2} \times 5^{2} = 20.$
