In the ring $\mathbb Z_5[X]$ find associated elements with $X^3+4X^2+3X+2$

I know that I must find $a \in \mathbb Z_5[X]$ such that $a|(X^3+4X^2+3X+2)$ and $(X^3+4X^2+3X+2)|a$. Assume that this $a$ exist we have:

$$\exists _{c\in \mathbb Z_5[X]} (X^3+4X^2+3X+2)=ac $$ $$\exists _{d\in \mathbb Z_5[X]} a=(X^3+4X^2+3X+2)d $$

However, I don't know how to find such $ a $ quickly
