Steps For Long Multiplication

First line up the numbers vertically and match the places from the right like this.

$$\begin{array}{c}\phantom{\times9}1620\\\underline{\times\phantom{999}20}\\\end{array}$$

Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 1620 with 0. Write the result 0 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times9}1620\\\underline{\times\phantom{999}20}\\\phantom{\times99999}0\\\end{array}$$

Now multiply the first number with the 2^{nd} digit in 2^{nd} number to get intermediate results. That is Multiply 1620 with 2. Write the result 3240 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times9}1620\\\underline{\times\phantom{999}20}\\\phantom{\times99999}0\\\underline{\phantom{\times}3240\phantom{9}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times9}1620\\\underline{\times\phantom{999}20}\\\phantom{\times99999}0\\\underline{\phantom{\times}3240\phantom{9}}\\\phantom{\times}32400\end{array}$$

Factor

$$2^{4}\times 3^{4}\times 5^{2}$$
