枚举出所有小于根号n 的因数 如果 没有除尽 剩下的是一个大的质因数 感悟: 应该算是比较水的题 但是由于很少做数论的题 所以总会觉得是因为有什么定理不会 所以不愿意去思考 也无从下手 以后碰到lcm和gcd的题 知道了有一个角度是分解质因数 #include <bits/stdc++.h>usingnamespacestd;intmain() { freop...
接下来问题等价于求三个数GCD为1,LCM为LCM/GCD的种类数了。 设这个商为X。 首先我们可以把X因数分解成X=(p1*x1)*(p2*x2)*……*(pn*xn); 单独拿出一个素数进行讨论,如果要设ABC分别为满足情况的三个数,那么Xa1,Xa2,Xa3中间必定有一个数为0,否则GCD就不为1了,同时必定有一个最大的为x1 这样我们...
