## Theorem
Let $c$ be a common divisor of two integers $a$ and $b$.
That is:
$a, b, c \in \Z: c \divides a \land c \divides b$
Then $c$ divides any integer combination of $a$ and $b$:
$\forall p, q \in \Z: c \divides \paren {p a + q b}$

Imagine I have a line segment defined by endpoints $p_1$ and $p_2$, and some 3-space coordinate $q$.
