我们将l,g进行素因子分解; 非常明显当g有l没有的素因子 和g的某一个因子的次数大于l的这个因子的次数的时候答案为0; 然后是有答案的情况下,我们设g中某一个因子数的次数为num1,l中这个因子的次数为num2; 那么在决定x,y,z在这个因子上的次数时我们要这样考虑,至少有一个为num1,至少有一个为 num2,然后...
【51nod1575】Gcd and Lcm(积性函数分析)(min_25筛) 传送门 题解: 首先我们知道gcdgcdgcd和lcmlcmlcm都是可以分质因子来算的,感觉可能会和积性函数沾边。 所以很显然地,我们设f(n)=∑i=1n∑j=1nlcm(gcd(i,n),gcd(j,n))f(n)=\sum\limits_{i=1}^n\sum\limits_{j=1}^nlcm(gcd(i,n),...
