We discuss heuristic and structural algorithms to construct long simple paths in the divisor graph D_n and the lcm-graph M_n and prove an inequality concerning the length-functions f(n) and g(n) of longest simple paths in D_n and M_n for certain natural numbers n. A number of examples are worked out in detail. (orig.)Available from TIB Hannover: RO 1945(304) / FIZ - Fachinformationszzentrum Karlsruhe / TIB - Technische InformationsbibliothekSIGLEDEGerman
