This function has been studied by many authors such as Broughan [4], Bordellés [3],Tanigawa and Zhai [18], Tóth [19], and others. Analytic properties for partial sums of the gcd-sum functionf(\gcd (j,k))were recently studied by Inoue and Kiuchi [8]. We recall that the symbol*d...
Let gcd(j,k) be the gnstest common divisor of the integers j and k. In this paper, we give several interesting asymptotic formulas for weighted averages of the gcd-sum function f(gcd(j,k)) and the function Sigma d vertical bar k,d(s)vertical bar j(f * mu)(d) for any positive...
Common Multiples of 4 and 10 = 20, 40, 60, 80 etc. All of those common multiples are multiples of the LCM(4,10) = 20 The GCM (Greatest Common Multiple) Does not exist! The LCM of Integers >= the greatest integer among all those integers i.e. LCM (4,10) = 20 . 20 is great...
The greatest common divisor (GCD) of 18 and 27 is 01:36 Which of the following is correct? 03:07 If f(0) = 1, f(l) = 4, f(2) = 10, then the value of Delta^2 f(0) is 03:58 If alpha, beta, gamma are the roots of the equation px^3 - qx + r = 0,... 01:23 ...

题面不给……题意:动态增减集合中元素个数,动态求gcd(i,j)==1gcd(i,j)==1的数的个数。 坦白地讲题解并没完全看懂……于是听lclc开了一会车(快开完时xyzxyz强行砸场导致烂尾),结合着自己理解又推一遍想明白了…… 在本题之中,我们设f(x)f(x)为gcd(i,j)==xgcd(i,j)==x的数的个数,g(x...

GCD and LCM: When given any two integer numbers, both of the numbers are divisors of the LCM (least common multiple) of the two numbers, because the LCM is a multiple of each of the numbers. However, as long as the two numbers ...
