Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times999}123\\\underline{\times\phantom{99}2781}\\\end{array}$$

Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 123 with 1. Write the result 123 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999}123\\\underline{\times\phantom{99}2781}\\\phantom{\times999}123\\\end{array}$$

Now multiply the first number with the 2^{nd} digit in 2^{nd} number to get intermediate results. That is Multiply 123 with 8. Write the result 984 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999}123\\\underline{\times\phantom{99}2781}\\\phantom{\times999}123\\\phantom{\times99}984\phantom{9}\\\end{array}$$

Now multiply the first number with the 3^{rd} digit in 2^{nd} number to get intermediate results. That is Multiply 123 with 7. Write the result 861 at the end leaving 2 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999}123\\\underline{\times\phantom{99}2781}\\\phantom{\times999}123\\\phantom{\times99}984\phantom{9}\\\phantom{\times9}861\phantom{99}\\\end{array}$$

Now multiply the first number with the 4^{th} digit in 2^{nd} number to get intermediate results. That is Multiply 123 with 2. Write the result 246 at the end leaving 3 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999}123\\\underline{\times\phantom{99}2781}\\\phantom{\times999}123\\\phantom{\times99}984\phantom{9}\\\phantom{\times9}861\phantom{99}\\\underline{\phantom{\times}246\phantom{999}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times999}123\\\underline{\times\phantom{99}2781}\\\phantom{\times999}123\\\phantom{\times99}984\phantom{9}\\\phantom{\times9}861\phantom{99}\\\underline{\phantom{\times}246\phantom{999}}\\\phantom{\times}342063\end{array}$$

Factor

$$3^{4}\times 41\times 103$$
