A number "n" can only be in S if "n^2" is multiple of 216; therefore, "n" MUST be a multiple of 36. So every member of S must be a multiple of 36, and all such positive multiples of 36 are in S. Therefore, because 36 is in S, the correct answers must be a factor of 36.

Web1 Cartier and Weil divisors Let X be a variety of dimension nover a eld k. We want to introduce two notions of divisors, one familiar from the last chapter. De nition 1.1. A Weil divisor of X is an n 1-cycle on X, i.e. a nite formal linear combination of codimension 1 subvarieties of X. Thus the Weil divisors form a group Z WebAug 7, 2024 · Simple approach is to traverse for every divisor of n 2 and count only those divisors which are not divisor of ‘n’. Time complexity of this approach is O(n). Efficient approach is to use prime factorization to count total divisors of n 2.A number ‘n’ can be represented as product of primes .Refer this to understand more.. Let for some primes p …
