Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times99}255\\\underline{\times\phantom{99}255}\\\end{array}$$

Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 255 with 5. Write the result 1275 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}255\\\underline{\times\phantom{99}255}\\\phantom{\times9}1275\\\end{array}$$

Now multiply the first number with the 2^{nd} digit in 2^{nd} number to get intermediate results. That is Multiply 255 with 5. Write the result 1275 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}255\\\underline{\times\phantom{99}255}\\\phantom{\times9}1275\\\phantom{\times}1275\phantom{9}\\\end{array}$$

Now multiply the first number with the 3^{rd} digit in 2^{nd} number to get intermediate results. That is Multiply 255 with 2. Write the result 510 at the end leaving 2 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}255\\\underline{\times\phantom{99}255}\\\phantom{\times9}1275\\\phantom{\times}1275\phantom{9}\\\underline{\phantom{\times}510\phantom{99}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times99}255\\\underline{\times\phantom{99}255}\\\phantom{\times9}1275\\\phantom{\times}1275\phantom{9}\\\underline{\phantom{\times}510\phantom{99}}\\\phantom{\times}65025\end{array}$$

Factor

$$3^{2}\times 5^{2}\times 17^{2}$$
