首先要引入多项式 f (x) 的 斯图姆序列： 记 f_0 (x)=f (x),~f_1 (x)=f' (x) ，用 带余除法 （余式前取减号）辗转相除得到. f_0=q_1f_1-f_2 , f_1=q_2f_2-f_3 , \cdots. f_ {k-2}=q_ {k-1}f_ {k-1}-f_k , f_ {k-1}=q_kf_k , 最后一个余式为0， f_k\neq 0 是 f 和 f' 的最大公因式，并且是 f_i,~0\leq i\leq k 的因式。 定义 g_j,~1\leq j\leq k-1 为 f_j/f_k ，也就是满足 f_j=g_jf_k . 当 f_k 不是常数时（有重根）定义 g_k=1 ；当 f_k 是常数时（无重根）定义 g_k=f_k .
