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) ...
我们发现,对于每个质因子,gcd是取较小值,lcm取较大值 f(lcm(x,y))∗f(gcd(x,y))=∏ki=1f(pmax(ai,bi)+min(ai,bi)i)f(lcm(x,y))∗f(gcd(x,y))=∏i=1kf(pimax(ai,bi)+min(ai,bi)) max(a,b)+min(a,b)=a+bmax(a,b)+min(a,b)=a+b 那么就有 f(lcm(x,y))∗f(gcd...
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 ...
将gcd与lcm素因子分解 如果gcd某个素因子的幂次pi大于lcm对应素因子的幂次qi 那就是凑不出 因为gcd肯定是lcm因子 如果pi<=qi xyz三个数中必有一个幂次为pi 必有一个为qi 因为gcd就是取得三者最小 lcm取最大 只剩一个数的幂次ti可变 当ti=pi或ti=qi时 可以产生3!/2!种可能 意思是把这三个幂次全...

Finds the greatest common divisor (GCD) and Least Common Multiple (LCM) of two, three and four numbers. Finds the prime factorization of numbers and shows it in the standard and exponential forms. Just enter two, three or four integers and tap "Calculate". ...
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 ...
