A novel way to derive the factoring of 63 = 7 * 9
Algebraic parity analysis of factoring of 63. Solve x0 * y0 = 63. The factoring of 63 = 3 * 3 * 7 is trivial, but here I am illustrating a novel way to derive the factoring. 63 is odd. Both x0 and y0 are odd. Set x0 = (2 x1 + 1) y0 = (2 y1 + 1) (2 x1 + 1) (2 y1 + 1) = 63 4 x1 y1 + 2 x1 + 2 y1 + 1 =... Sign in to see full entry.
