Default New Fermat factor found!

Just received a mail from Payam Samidoost:

Code:
After a long search I have finally found a new Fermat divisor:

89*2^472099+1 which divides F472097.
I think it may interest those of you involved in Fermat numbers factoring.

Sorry for cross-posting in Lounge

New Fermat factor found by Jim Fougeron! It's the second this year.

The factor is 21*2287388 which divides F287384.

Congratulations Jim!

Well... I pasted too fast and didn't check it

The factor is 211*2287388 which divides F287384.

Sorry for the typo.
