题目链接: https://cn.vjudge.net/problem/23709/origin 本题其实有坑 数据大小太大, 2的32次方,故而一定是取巧的算法,暴力不可能过的 思路是最大公因数的倍数是最小公倍数,又有a <= b所以可以知道 a = gcd, b = lcm AC代码如下: #include <cstdio> #define ll long long using namespace std; int main() { int T; scanf("%d&quo
并不重要的前言 最近学习了一些数论知识,但是自己都不懂自己到底学了些什么qwq,在这里把知识一并总结起来. 也不是很难的gcd和lcm 显而易见的结论: 为什么呢? 根据唯一分解定理: a和b都可被分解为素因子的乘积,形如: 则显而易见的有一下结论: 相乘,得: 得证 几种求gcd的算法 欧几里得算法(辗转相除法) 辗转相减法(优化:stein_gcd) 欧几里得算法 基于事实: 实现: int gcd(int a, int b){ ) ? a : gcd( b , a % b) ; } 简短而

GCD and LCM Descriptions: Write a program which computes the greatest common divisor (GCD) and the least common multiple (LCM) of given a and b. Input Input consists of several data sets. Each data set contains a and b separated by a single space in
GCD _ LCM 是给你两个数A B 的最大公约数, 以及最小公倍数 the greatest common divisor and the least common multiply ! 最大公约数最简单.最常见的算法,就是辗转相除法 : 假设 GCD(A , B) ; A / B = P ; A % B = Q; 那么 A = B P + Q; GCD(B, Q); GCD (A , B) % GCD (B , Q) = 0 : 因为 A 的表达式当中包括了 B .
