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) means the least ...
1.一个数是可以拆分成多个质因子相乘,如果一个数是许多个数字的最大公因数,那么最大公因数对应质因子位置上面的指数应该是这些质因子对应指数的最小值;最小公倍数则是对应质因子位置上面的指数最大值 2.容斥定理:以3个集合A,B,C为例,我们如果需要求出A B C,那么实际上我们是以这样一个式子来解决...

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...

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 ...
