Пошаговое объяснение:
1)
220 = 2 * 2 * 5 * 11
165 = 3 * 5 * 11
77 = 7 * 11
НОД (220; 165; 77) = 11
2)
63 = 3 * 3 * 7
42 = 2 * 3 * 7
168 = 2 * 2 * 2 * 3 * 7
НОД (63; 42; 168) = 3 * 7 = 21
3)
230 = 2 * 5 * 23
92 = 2 * 2 * 23
138 = 2 * 3 * 23
НОД (230; 92; 138) = 2 * 23 = 46
4)
650 = 2 * 5 * 5 * 13
260 = 2 * 2 * 5 * 13
НОД (42; 650; 260) = 2
