Table of n, a(n) for n=2..10.

|
FORMULA
|
a(n)=Max{x; f[x]=n!}, where x has no digit=1 and f[x_] := Apply[Times, IntegerDigits[x]].
|
|
|
EXAMPLE
|
Maximal solutions are obtained from concatenation of distinct all prime-factors which has one decimal digit. The sequence is finite because n! for n>10 has 2-digit prime-factors.
