It is well-known that a divisor d > 0 of the positive integer n is called unitary, if dδ = n and (d, δ) = 1. For integers a, b not both zero, let the symbol (a, b)** denote the greatest unitary divisor of both a and b. A divisor d>0 of the positive integer n is called bi-unitary, if dδ = n and (d, δ)** = 1.

Abstract


It is well-known that a divisor d > 0 of the positive integer n is called unitary, if dδ = n and (d, δ) = 1. For integers a, b not both zero, let the symbol (a, b)** denote the greatest unitary divisor of both a and b. A divisor d>0 of the positive integer n is called bi-unitary, if dδ = n and (d, δ)** = 1.
