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...
If S is factor-closed, we calculate the inverses of the GCD and LCM matrices on S and show that [S](S) 1 is an integral matrix. We also extend a result of H. J. S. Smith by calculating the determinant of [ S ] when ( x i , x j )∈ S for 1 i , j n ....

f(gcd(i,j))∗f(lcm(i,j)) =∏f(pmin(q1,q2))∗∏f(pmax(q1,q2)) =∏f(i)∗f(j) 于是: Ans =∑ni=1∑nj=1f(gcd(i,j))∗f(lcm(i,j)) =(∑ni=1f(i))2 (∑ni=1f(i) =∑ni=1∑d|iμ(d)∗d =∑ni=1μ(i)∗i∗⌊ni⌋ 那么用杜教筛筛一下...
