Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times}400000\\\underline{\times\phantom{}70000}\\\end{array}$$

Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 400000 with 0. Write the result 0 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times}400000\\\underline{\times\phantom{}70000}\\\phantom{\times}0\\\end{array}$$

Now multiply the first number with the 2^{nd} digit in 2^{nd} number to get intermediate results. That is Multiply 400000 with 0. Write the result 0 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times}400000\\\underline{\times\phantom{}70000}\\\phantom{\times}0\\\phantom{\times}0\phantom{9}\\\end{array}$$

Now multiply the first number with the 3^{rd} digit in 2^{nd} number to get intermediate results. That is Multiply 400000 with 0. Write the result 0 at the end leaving 2 spaces to the right like this.

$$\begin{array}{c}\phantom{\times}400000\\\underline{\times\phantom{}70000}\\\phantom{\times}0\\\phantom{\times}0\phantom{9}\\\phantom{\times}0\phantom{99}\\\end{array}$$

Now multiply the first number with the 4^{th} digit in 2^{nd} number to get intermediate results. That is Multiply 400000 with 0. Write the result 0 at the end leaving 3 spaces to the right like this.

$$\begin{array}{c}\phantom{\times}400000\\\underline{\times\phantom{}70000}\\\phantom{\times}0\\\phantom{\times}0\phantom{9}\\\phantom{\times}0\phantom{99}\\\phantom{\times}0\phantom{999}\\\end{array}$$

Now multiply the first number with the 5^{th} digit in 2^{nd} number to get intermediate results. That is Multiply 400000 with 7. Write the result 2800000 at the end leaving 4 spaces to the right like this.

$$\begin{array}{c}\phantom{\times}400000\\\underline{\times\phantom{}70000}\\\phantom{\times}0\\\phantom{\times}0\phantom{9}\\\phantom{\times}0\phantom{99}\\\phantom{\times}0\phantom{999}\\\underline{\phantom{\times}2800000\phantom{9999}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times}400000\\\underline{\times\phantom{}70000}\\\phantom{\times}0\\\phantom{\times}0\phantom{9}\\\phantom{\times}0\phantom{99}\\\phantom{\times}0\phantom{999}\\\underline{\phantom{\times}2800000\phantom{9999}}\\\phantom{\times}-2064771072\end{array}$$

Factor

$$2^{11}\times 5^{9}\times 7$$
