Táboa de divisores

Un divisor dun número enteiro n é un enteiro m para o que n/m é tamén enteiro (que necesariamente será tamén divisor de n). Por exemplo, 4 é divisor de 28 porque 28/4 = 7 (e 7 é tamén divisor de 28).

Se m é divisor de n tamén o é −m. A táboa só lista divisores positivos.

 Clave da táboa 
A táboa seguinte dá os divisores dos números entre 1 e 1000.

d(n) é o número de divisores positivos de n, incluíndo 1 e n.
σ(n) é a súma de todos os divisores positivos de n, incluíndo 1 e n.
s(n) é a suma dos divisores propios de n, que non inclúen n. Polo tanto, s(n) = σ(n) − n.

 Observacións 
Un número é perfecto se é igual á suma dos seus divisores propios, é dicir, s(n) = n. Os únicos números perfectos entre 1 e 1000 son 6, 28 e 496.
Dous números son amigos se a suma dos divisores propios dun deles coincide co outro e viceversa. O concepto pode xeneralizarse a conxuntos de máis de dous números (números sociábeis). Os únicos números amigos menores que 1000 son 220 e 284.
Un número é defectivo se é maior cá suma do seus divisores propios, é dicir, s(n) < n.
Un número é abundante se é menor cá suma do seus divisores propios, é dicir, s(n) > n.
Un número primo só ten 1 e el mesmo como divisores, polo que d(n) = 2. Os números primos son sempre defectivos, porque s(n)=1
