# the family members, relatives, and pets of a positive integer

(suggested new terminology)

Definition 1. The family members of a positive integer n are the divisors of n.

Definition 2. The relatives of a positive integer n are the positive integers not exceeding n that are not relatively prime to n.

Definition 3. The pets of a positive integer n are the positive integers not exceeding n that are relatively prime to n.

Remark: Euler’s phi function tells how many pets a given positive integer has.
