AOJ 0005 GCD and LCM 题意:求两数最大公约数和最小公倍数。 类型:辗转相除法 算法:gcd(a,b)=gcd(b,a%b),lcm(a,b)=a*b/gcd(a,b)。 #include <cstdio> #include <iostream> using namespace std; int gcd(int a, int b) { for(int t; t = a % b; a = b, b = t); return ...
对于两个整数x,y,他们的lcm为x和y的所有质因子取最大指数的积, 他们的gcd为x和y所有的质因子取最小指数的积, 题意为每对i,j(i<j)求出他们的最小公倍数,再对所有的最小公倍数求他们的最大公因数g 对于所有的质因子,如果该质因子出现的次数<n-1,那么必定存在i,j,使得他们的lcm分解 之后该质因子的...
Problem Description Given two positive integers G and L, could you tell me how many solutions of (x, y, z) there are, satisfying that gcd(x, y, z) = G and lcm(x, y, z) = L? Note, gcd(x, y, z) means the greatest common divisor of x, y and z, while lcm(x, y, z) ...

HDU - 4497 GCD and LCM 题意:给出三个数的gcd,lcm,求这三个数的全部的可能 思路 :设x,y,z的gcd为d,那么设x=d*a,y=d*b,z=d*c。a,b。c肯定是互质的。那么lcm=d*a*b*c,所以我们能够得到a*b*c=lcm/gcd=ans,将ans分解因数后,那么每次都要分配每一个因数的个数,如果某个因数的个数为n...
We explore new ways of computing a least common multiple (LCM) and a greatest common divisor (GCD) of polynomialsrepresented in Lagrange basis, or in other words, by their interpolation data. By considering the underlying linear system ofequations, we show that this can be done without first ...
