least common multiple

For $a,b \in \mathbb{N}$ two positive natural numbers, their **least common multiple** $LCM(a,b) \in \mathbb{N}$ is the smallest natural number that is divisible by both $a$ and $b$, i.e. such that there exist $n_a, n_n \in \mathbb{N}$ with $n_a \cdot a = n_b \cdot b = LCM(a,b)$.

- greatest common divisor?
