应该说,整数的因数分解是一个易于理解、清楚明白的问题,但并不是一个简单的问题.较小整数的因数分解是一个小学算术问题.但充分大的数,例如一个50位的整数的因数分解问题就是一个超级数学难题了,用小学学过的试除法,即使采用电子计算机,一个人一辈子也做不出来;而且,假设人类? It should be said that the factorization of integers is an easy-to-understand, clear question, but it is not a simple one. The factorization of smaller integers is an elementary arithmetic problem, but a sufficiently large number, such as a 50-bit integer The problem of factorization is a super mathematics problem. With the trial division method that has been studied in primary schools, even if an electronic computer is used, one cannot do it for a lifetime. And, suppose human beings?
