Question

Write $1360$ in prime factorisation form.

Answer 1

We have,

$$\begin{gathered} 1360=2\times 680 \\ 1360=2\times 2\times 340 \\ 1360=2\times 2\times 2\times 170 \\ 1360=2\times 2\times 2\times 2\times 85 \\ 1360=2\times 2\times 2\times 2\times 5\times 17 \end{gathered}$$

Therefore, the prime factorisation form of $1360$ is $1360=2\times 2\times 2\times 2\times 5\times 17$.
