If you are doing this what you adviced me to do then DON'T DO SO!. Find area interesting for you and unsolved problem interesting for you and try to solve it. People will tell you that your work is worthless and this is what they will think. It is because everybody thinks that only his area of interest is worthy to pay attentions.

I am amazed that so much has been written in this thread about the factorization of F7. As far as I am concerned you pass the number into YAFU, wait a short while, and pick up the factors out the other end. End of story, pass on to the next number.
Since you will have done this one a few years ago, with all the others you will have done in the meantime you should be looking at F77 now, or even F777, and certainly not F7. Last fiddled with by BudgieJane on 20131116 at 17:22 Reason: Correction of grammatical error.

Yes, it is a wonderful idea. I waited less than 1 sec. for a result. Quote:
I don't like number 7. I would better do F88.

F88 would take too long to write out manually. Might I suggest F20 instead? Its a nice, round number, and much smaller :)

Even this is no longer true. You didn't even have a proof until Anand Nair corrected you.
