reasons why a LL test would be redundant

Hi,

I've been doing a LL on this exponent now for over 5 month but the

prime95 program says it's a redundant effort.

67871197

I know it's prime so I can't work out why it would be redundant. Would it be because it's already been tested ?

That number has a known factor. That's why it's redundant.

Right, thanks. I didn't realise there was a way to check.
