Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times99}1580\\\underline{\times\phantom{999}257}\\\end{array}$$

Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 1580 with 7. Write the result 11060 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}1580\\\underline{\times\phantom{999}257}\\\phantom{\times9}11060\\\end{array}$$

Now multiply the first number with the 2^{nd} digit in 2^{nd} number to get intermediate results. That is Multiply 1580 with 5. Write the result 7900 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}1580\\\underline{\times\phantom{999}257}\\\phantom{\times9}11060\\\phantom{\times9}7900\phantom{9}\\\end{array}$$

Now multiply the first number with the 3^{rd} digit in 2^{nd} number to get intermediate results. That is Multiply 1580 with 2. Write the result 3160 at the end leaving 2 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}1580\\\underline{\times\phantom{999}257}\\\phantom{\times9}11060\\\phantom{\times9}7900\phantom{9}\\\underline{\phantom{\times}3160\phantom{99}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times99}1580\\\underline{\times\phantom{999}257}\\\phantom{\times9}11060\\\phantom{\times9}7900\phantom{9}\\\underline{\phantom{\times}3160\phantom{99}}\\\phantom{\times}406060\end{array}$$

Factor

$$2^{2}\times 5\times 79\times 257$$
