Решение:

1. Умножение:

   \[ 241 \times 467 \]

   \( \begin{array}{c} \phantom{00}\times 241 \\ \underline{\phantom{0}467} \\ \phantom{0}1687 \\ 1446 \phantom{0} \\ 964 \phantom{00} \\ \underline{\phantom{}} \\ 112547 \end{array} \)

   \[ 621 \times 628 \]

   \( \begin{array}{c} \phantom{00}\times 621 \\ \underline{\phantom{0}628} \\ \phantom{0}4968 \\ 1242 \phantom{0} \\ 3726 \phantom{00} \\ \underline{\phantom{}} \\ 390088 \end{array} \)

   \[ 819 \times 178 \]

   \( \begin{array}{c} \phantom{00}\times 819 \\ \underline{\phantom{0}178} \\ \phantom{0}6552 \\ 5733 \phantom{0} \\ 819 \phantom{00} \\ \underline{\phantom{}} \\ 145782 \end{array} \)

   \[ 168 \times 743 \]

   \( \begin{array}{c} \phantom{00}\times 168 \\ \underline{\phantom{0}743} \\ \phantom{00}504 \\ \phantom{0}672 \phantom{0} \\ 1176 \phantom{00} \\ \underline{\phantom{}} \\ 124824 \end{array} \)
