Biggest factor I found so far (through P-1):

4060777630590324655274324247844481

NOTE: How to compute the number of bits? I don´t know any decimal to binary converter capable of handling numbers this big.

http://mersenne-aries.sili.net/ has one specifically for computing the bit size of factors. It's 111.65 bits. Other options include anything with support for large numbers and a logarithm, (any base) such as Wolfram Alpha or PARI/GP (use log(x)/log(y) with any base logarithm to get the base y logarithm).

Writing one for yourself is instructive and comparatively trivial.
I say this having written one in Basic a few years back.

Of course you can approximate it by dividing the number of digits by log₁₀2.

Thank you both for your answers.

I have broke into the top rank 100 overall due partly to the dropping out of the v4 stats.

Within the past week:

* Crossed over 1,000 GHz-days of trial factoring
* Crossed over 10,000 GHz-days of total GIMPS computing
* Number of GHz-years of GIMPS computing now surpasses the number of years I've been alive - 28.24 vs. 27.18.
* Crossed over 12,000 completed TF assignments (now stand at 12,001)
* Crossed over 200 completed LL assignments (now stand at 205)

I'm #66 in LL (#84 across all work types) for the past year, and #210 lifetime across all work types. I have an LL scheduled to come in on average every 1-3 days.

Quite an accomplishment...

Today marks ten years of being happily married!

Congratulations.
I forget. Is that a tin wedding?
Mine lasted ~20 years, enough to launch me alone, impoverished,
jobless and homeless into middle age.
I'll probably think of, find and post a song in a few minutes

Best Wishes,
David

This is probably an old one but....

I still remember a few years back when a friend of mine announced it was their anniversary, then turned to his wife and with a grin said "Yup, 10 happy years."
She quickly corrected him: "No dear, we've been married 23 years!?"
He simply said: "I know", paused while we all shifted our feet nervously, then gave out a big grin and she kicked him in the shins.
Then we all laughed.

I'll have to remember that one.
