Relations among the multiplicative functions discussed above include:
 
* <math>\epsilonmu</math> * 1 = <math>\muepsilon</math> * 1 (the [[Möbius inversion formula]])
* (<math>\phimu</math> Id<sub>''k''</sub>) * Id<sub>''k''</sub> = <math>\muepsilon</math> *(generalized IdMöbius inversion)
* <math>\phi</math> * 1 = Id
* ''d'' = 1 * 1
* <math>\sigma</math> = Id * 1 = <math>\phi</math> * ''d''
