What is the largest integer which always divides n7−n for any n?

Answer 1

N must be an integer or else all bets are off !!!!

Assuming you mean n^7 - n = n(n^6 - 1) then

the largest integer that always divides shall be n

But if you mean 7n -n = 6n, then it is 6 if n<6 or n if n>6.

Please repost

Answer 2

I guess you mean n⁷ - n which, of course, is always divisible by n.
