COMMENTS
|
William Stanley Jevons apparently thought it was unlikely that anyone could factor this number. On modern computers, however, this task takes just a fraction of a second. For example, PARI almost instantly returns 8616460799 = 89681 * 96079.
Donald E. Knuth points out that "Fermat could have factored N in less than 10 minutes, on the back of an envelope".
