It's worth noting that A160376(11) is wrong by any reasonable
interpretation, as 33916801 does not divide 11! + 1.
I would mark it as a dupe.

For example, 9!+1 = 362881 = 19*71*269, so the largest divisor is 71*269=19099, but the largest prime divisor is 269, which is the value in the sequence. I think the author probably meant "Largest prime divisor", but this would make it a duplicate of A002583.
