# Polynomial's Common Multiple

Algebra Level 2

$\begin{eqnarray} f(x) &=& p(x)(x-1) +1 \\ f(x) &=& q(x)(x-2) +1 \\ f(x) &=& r(x)(x-3) +1 \end{eqnarray}$

Let $$f(x)$$ be a cubic monic polynomial, and $$p(x), q(x), r(x)$$ be quadratic polynomials satisfying the system of equations above.

What is the value of $$f(4)$$?
