The Prizes and Records
The following table gives an overview over all RSA numbers.
- The challenge numbers in white lines are numbers expressed in base 10, while the challenge numbers in yellow lines are numbers expressed in base 2. The prizes for RSA-576 and RSA-640 have been awarded. The remaining prizes have been retracted since the challenge became inactive in 2007.

^ * The number was factored after the challenge became inactive.
^ ** RSA-129 was not part of the RSA Factoring Challenge, but was related to a column by Martin Gardner in Scientific American.
^ *** RSA-170 was also independently factored by S. A. Danilov and I. A. Popovyan two days later.

Famous quotes containing the words prizes and/or records:
“She prizes not such trifles as these are.
The gifts she looks from me are packed and locked
Up in my heart, which I have given already,
But not delivered.”
—William Shakespeare (1564–1616)
“Although crowds gathered once if she but showed her face,
And even old men’s eyes grew dim, this hand alone,
Like some last courtier at a gypsy camping-place
Babbling of fallen majesty, records what’s gone.”
—William Butler Yeats (1865–1939)
