Решение:

1. 11 и 12:

   НОК(11, 12) = 11 × 12 = 132

2. 16 и 18:

   16 = 2⁴

   18 = 2 × 3²

   НОК(16, 18) = 2⁴ × 3² = 16 × 9 = 144

3. 125 и 75:

   125 = 5³

   75 = 3 × 5²

   НОК(125, 75) = 3 × 5³ = 3 × 125 = 375

4. 190 и 920:

   190 = 2 × 5 × 19

   920 = 2³ × 5 × 23

   НОК(190, 920) = 2³ × 5 × 19 × 23 = 8 × 5 × 19 × 23 = 17480

5. 24, 68 и 162:

   24 = 2³ × 3

   68 = 2² × 17

   162 = 2 × 3⁴

   НОК(24, 68, 162) = 2³ × 3⁴ × 17 = 8 × 81 × 17 = 11016

6. 588 и 252:

   588 = 2² × 3 × 7²

   252 = 2² × 3² × 7

   НОК(588, 252) = 2² × 3² × 7² = 4 × 9 × 49 = 1764

7. 675 и 995:

   675 = 3³ × 5²

   995 = 5 × 199

   НОК(675, 995) = 3³ × 5² × 199 = 27 × 25 × 199 = 134325

8. 924 и 396:

   924 = 2² × 3 × 7 × 11

   396 = 2² × 3² × 11

   НОК(924, 396) = 2² × 3² × 7 × 11 = 4 × 9 × 7 × 11 = 2772

9. 995 и 825:

   995 = 5 × 199

   825 = 3 × 5² × 11

   НОК(995, 825) = 3 × 5² × 11 × 199 = 3 × 25 × 11 × 199 = 164025
