Решение:

  1. 12 ⋅ 15 ⋅ 4 = (22 ⋅ 3) ⋅ (3 ⋅ 5) ⋅ 22 = 24 ⋅ 32 ⋅ 5 = 16 ⋅ 9 ⋅ 5 = 144 ⋅ 5 = 720
  2. 24 ⋅ 26 = (23 ⋅ 3) ⋅ (2 ⋅ 13) = 24 ⋅ 3 ⋅ 13 = 16 ⋅ 3 ⋅ 13 = 48 ⋅ 13 = 624
  3. 33 ⋅ 77 ⋅ 11 ⋅ 15 = (3 ⋅ 11) ⋅ (7 ⋅ 11) ⋅ 11 ⋅ (3 ⋅ 5) = 32 ⋅ 5 ⋅ 7 ⋅ 113 = 9 ⋅ 5 ⋅ 7 ⋅ 1331 = 45 ⋅ 7 ⋅ 1331 = 315 ⋅ 1331 = 419115
  4. 9 ⋅ 72 ⋅ 37 = 32 ⋅ (23 ⋅ 32) ⋅ 37 = 23 ⋅ 34 ⋅ 37 = 8 ⋅ 81 ⋅ 37 = 648 ⋅ 37 = 23976
  5. 35 ⋅ 17 ⋅ 34 = (5 ⋅ 7) ⋅ 17 ⋅ (2 ⋅ 17) = 2 ⋅ 5 ⋅ 7 ⋅ 172 = 10 ⋅ 7 ⋅ 289 = 70 ⋅ 289 = 20230
