242 = (2 * 121) = (2 * 11* 11) = 112;

363 = (3 * 121) = (3 * 11 * 11) = 113;

484 = (4 * 121) = (2 * 2 * 11 * 11) = 2 * 11 = 22;

847 = (7 * 121) = (7 * 11 * 11) = 117;

605 = (5 * 121) = 115;

882 = (2 * 441) = (2 * 147 * 3) = (2 * 3 * 49 * 3) = 3(2 * 49) = 3(2 * 7 * 7) = 3 * 72 = 212;

720 = (2 * 360) = (2 * 6 * 60) = (2 * 2 * 3 * 60) = 2(3 * 60) = 2(3 * 2 * 3 * 5 * 2) = 2 * 3 * 25 = 125;

2178 = (1089 * 2) = (33 * 33 * 2) = 332;

(20 + 45) * 5 = 20 * 5 + 45 * 5 = 100 + 225 = 10 + 15 = 25;

(63 - 28) * 7 = 63 * 7 - 28 * 7 = 441 - 196 = 21 - 14 = 7;

(3 + 52) * 6 = 3 * 6 + 52 * 6 = 18 + 512 = 32 + 102 = 132;

(512 - 33) * 23 = 512 * 2 3 - 33 * 23 = 1036 - 6 * 3 = 60 - 18 = 42;

(23 + 1)(23 - 1) = (23)²- 1 = 4 * 3 - 1 = 11;

(2 - 3)(4 + 23) = (2 - 3) * 2 * (2 + 3) = 2 * (4 - 3) = 2;

(6 - 32)(2 - 2) = 3 * (2 - 2)(2 - 2) = 3 * (2 - 2)² = 3 * (4 - 42 + 2 = 3 * (6 - 42) = 18 - 122;

(4 + 37)(37 - 4) = (37 + 4)(37 - 4) = (37)² - 16 = 9 * 7 - 16 = 63 - 16 = 47.
