整除性问题的递推证法陕西华阴黄河工程机械厂中学李建章整除性问题是数学竞赛中的常见命题，通常的证法是数学归纳法或利用较强的变形技巧．本文给出与自然数ｎ有关的整除性问题的简单的递推证法，供参考．命题１设均为非负整数．若且，则ｍ｜ｆ（ｎ）．由递推性易知命题... Recursive proof of divisibility issues Li Jianzhang, the divisibility issue in Shaanxi Huayin Huanghe Construction Machinery Middle School, is a common proposition in mathematics competitions. The usual proofs are mathematical induction methods or the use of strong deformation techniques. This article gives a simple recursive proof of the divisibility problem related to the natural number n for reference. Proposition 1 is set to non-negative integers. If and, then m|f(n). Recursively easy to know propositions...
