In the wake of the false prime report a few months ago, we added a few

Hello all,
This morning a new Mersenne Prime was reported to the primenet server.
It will be the new largest known prime but is less than 10 million digits.

Now 2^1 + 1 = 3 is divisible by 3, therefore 2^p+1 is divisible by 3 for

To Whom It May Concern:
I have devised a method of easily figuring out
approximately how many prime numbers are before
a given prime. Here it is: since the natural
logarithm of a number increases +2.3 for every
power of 10, the 39th Mersenne Prime, since it

Possibly "Mersenne prime candidate", not "Mersenne prime"? 33219281 is prime,
but my guess is somebody has checked 2^33219281-1 long ago, and
uestion
of the FAQ which was "How many digits are in a given Mp?".
The simple formula;
INT [ exponent / 3.321928094887 + 1] = number of decimal digits in
2^exponent-1
would have been more straight forward to us novices.
Thanks for your help.

onent 33,219,277 has 9,999,999 digits (the least integer greater
