Multiply. Show your work. \( \begin{array}{l}2,241 \\ \times \quad 6 \\ 78\end{array} \)

To multiply \(2,241\) by \(678\), we can break it down as follows: 1. Multiply \(2,241\) by \(8\): \[ 2,241 \times 8 = 17,928 \] 2. Multiply \(2,241\) by \(70\) (or \(7\) shifted one place to the left): \[ 2,241 \times 70 = 156,870 \] 3. Multiply \(2,241\) by \(600\) (or \(6\) shifted two places to the left): \[ 2,241 \times 600 = 1,344,600 \] 4. Now we can add these results together: \[ 17,928 + 156,870 + 1,344,600 = 1,515,398 \] So, \(2,241 \times 678 = 1,515,398\).
