Factors of Mersenne Numbers
I maintain a comprehensive list of factors of Mersenne numbers and Mersenne composites, through some N (which continues to grow).
The links below give lists of the smallest Mersenne number or Mersenne composite
Mq = 2^q - 1, each p divides, in the form

p | Mq   or p | Rn,
where "p" is the (base 10) prime factor [1 or 7 (mod 8)], and "Mq" gives the prime power of the Mersenne number, or "Rn" gives the composite power of the Mersenne number. The vertical bar is used in the normal mathematical sense to mean "divides".
