 OFFSET 1,6 LINKS MATHEMATICA Table[If[n==1, 0, Max@@Length/@Split[Rest[Divisors[n]], #2==#1+1&]], {n, 100}] CROSSREFS Records occur at A328448. Positions of 0's and 1's are A088725. The version that looks at all divisors (including 1) is A055874. The number of successive pairs of divisors > 1 of n is A088722(n). The Heinz number of the multiset of run-lengths of divisors of n is A328166(n). The longest run of nontrivial divisors of n is A328458(n). Cf. A000005, A027750, A129308, A181063, A199970, A328162, A328195, A328449.
