Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times999}643\\\underline{\times\phantom{999}549}\\\end{array}$$

Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 643 with 9. Write the result 5787 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999}643\\\underline{\times\phantom{999}549}\\\phantom{\times99}5787\\\end{array}$$

Now multiply the first number with the 2^{nd} digit in 2^{nd} number to get intermediate results. That is Multiply 643 with 4. Write the result 2572 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999}643\\\underline{\times\phantom{999}549}\\\phantom{\times99}5787\\\phantom{\times9}2572\phantom{9}\\\end{array}$$

Now multiply the first number with the 3^{rd} digit in 2^{nd} number to get intermediate results. That is Multiply 643 with 5. Write the result 3215 at the end leaving 2 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999}643\\\underline{\times\phantom{999}549}\\\phantom{\times99}5787\\\phantom{\times9}2572\phantom{9}\\\underline{\phantom{\times}3215\phantom{99}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times999}643\\\underline{\times\phantom{999}549}\\\phantom{\times99}5787\\\phantom{\times9}2572\phantom{9}\\\underline{\phantom{\times}3215\phantom{99}}\\\phantom{\times}353007\end{array}$$

Factor
