What is the largest prime factor of the number 600851475143 ? 2. 解法(by java in Eclipse) way1 way2 注:利用分解质因数的方法,从小向大用质数整除(如果此质数恰好是n的因数的话)n,即不断的减小n的规模,最后即可求的最大质因数。 法二,采用了递归的方法易于理解,但是内存消耗较大;建议用法一。
The prime factors of 13195 are 5, 7, 13 and 29.What is the largest prime factor of the number 600851475143 ? 题解 朴素枚举 我们可以仿照前两个问题的思路,枚举每一个数,判断是否是素数&是否是600851475143的因数。由于数字很大,加上这样做的复杂度过高,我不再给出代码。 筛法 我们可以利用筛法先筛出...
