You asked:

Find the least common multiple of the following numbers: \(7, 5, 4\).

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 $7$ is $7$.

The prime factorization of $5$ is $5$.

The prime factorization of $4$ is $2^{2}$.

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