Помогите пожалуйста!!!

▪1) НОД (48, 84) = 12
48 = 2 × 2 × 2 × 2 × 3
84 = 2 × 2 × 3 × 7
НОД (48, 84) = 2 × 2 × 3 = 12

▪2) НОД (70, 98) = 14
70 = 2 × 5 × 7
98 = 2 × 7 × 7
НОД (70, 98) = 2 × 7 = 14

▪3) НОД (16, 45) = 1
16 = 2 × 2 × 2 × 2
45 = 3 × 3 × 5
НОД (16, 45) = 1

▪4) НОД (52, 78) = 26
52 = 2 × 2 × 13
78 = 2 × 3 ×13
НОД (52, 78) = 2 × 13 = 26

▪5) НОД (44, 65) = 1
44 = 2 × 2 × 11
65 = 5 × 13
НОД (44, 65) = 1

▪6) НОД (72, 96) = 24
72 = 2 × 2 × 2 × 3 × 3
96 = 2 × 2 × 2 × 2 × 2 × 3
НОД (72, 96) = 2 × 2 × 2 × 3 = 24

▪7) НОД (78, 117, 195) = 39
78 = 2 × 3 × 13
117 = 3 × 3 × 13
195 = 3 × 5 × 13
НОД (72, 96) = 3 × 13 = 39

▪8) НОД (110, 154, 286) = 22
110 = 2 × 5 ×11
154= 2 × 7 ×11
286 = 2 × 11 × 13
НОД (110, 154, 286) = 2 × 11 = 22

▪9) НОД (90, 126, 162) = 18
90 = 2 × 3 × 3 × 5
126= 2 × 3 × 3 × 7
162 = 2 × 3 × 3 × 3 × 3
НОД (90, 126, 162) = 2 × 3 × 3 = 18
