Number
$2 \, 759 \, 640$ (two million, seven hundred and fifty-nine thousand, six hundred and forty) is:


 * $2^3 \times 3 \times 5 \times 13 \times 29 \times 61$


 * The $3$rd and last positive integer $n$ after $15$, $22 \, 440$ such that $\pm n$ allows $x^5 - x + n$ to be factorized into the product of an irreducible quadratic and an an irreducible cubic:
 * $x^5 - x + 2 \, 759 \, 640 = \left({x^2 + 12 x + 377}\right) \left({x^3 - 12 x^2 - 233 x + 7320}\right)$
