Solve 720*15

$$720 \times 15$$

Evaluate

$$10800$$

Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times99}720\\\underline{\times\phantom{999}15}\\\end{array}$$

Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 720 with 5. Write the result 3600 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}720\\\underline{\times\phantom{999}15}\\\phantom{\times9}3600\\\end{array}$$

Now multiply the first number with the 2^{nd} digit in 2^{nd} number to get intermediate results. That is Multiply 720 with 1. Write the result 720 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}720\\\underline{\times\phantom{999}15}\\\phantom{\times9}3600\\\underline{\phantom{\times9}720\phantom{9}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times99}720\\\underline{\times\phantom{999}15}\\\phantom{\times9}3600\\\underline{\phantom{\times9}720\phantom{9}}\\\phantom{\times}10800\end{array}$$

Factor

$$2^{4}\times 3^{3}\times 5^{2}$$
