Ответ:

  1. \(156 = 2 \cdot 78 = 2^2 \cdot 39 = 2^2 \cdot 3 \cdot 13\).

  2. \(462 = 2 \cdot 231 = 2 \cdot 3 \cdot 77 = 2 \cdot 3 \cdot 7 \cdot 11\).

  3. \(1008 = 2 \cdot 504 = 2^2 \cdot 252 = 2^3 \cdot 126 = 2^4 \cdot 63 = 2^4 \cdot 3^2 \cdot 7\).

  4. \(1872 = 2 \cdot 936 = 2^2 \cdot 468 = 2^3 \cdot 234 = 2^4 \cdot 117 = 2^4 \cdot 3^2 \cdot 13\).

  5. \(2080 = 2 \cdot 1040 = 2^2 \cdot 520 = 2^3 \cdot 260 = 2^4 \cdot 130 = 2^5 \cdot 65 = 2^5 \cdot 5 \cdot 13\).

  6. \(4550 = 2 \cdot 2275 = 2 \cdot 5 \cdot 455 = 2 \cdot 5^2 \cdot 91 = 2 \cdot 5^2 \cdot 7 \cdot 13\).
