Web25 de set. de 2024 · In an integral domain, elements $a$ and $b$ are simultaneously divisible by each other ($a b$ and $b a$) if and only if they are associated, i.e. $a \ ub$, where $u$ is an invertible element. Two associated elements generate the same principal ideal. The unit divisors coincide, by definition, with invertible elements. Web18 de mai. de 2009 · For each positive integer k and real x > 1, denote by N ( v, k; x) the number of positive integers n ≦ x for which σ v ( n) is not divisible by k. Then Watson [ 6] has shown that, when v is odd, as x → ∞; it is assumed here and throughout that v and k are fixed and independent of x.

A divisibility rule is a shorthand and useful way of determining whether a given integer is divisible by a fixed divisor without performing the division, usually by examining its digits. Although there are divisibility tests for numbers in any radix, or base, and they are all different, this article presents rules and examples only for decimal, or base 10, numbers.
