$$16 \times 45 =$$

Evaluate

$$720$$

Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times9}16\\\underline{\times\phantom{9}45}\\\end{array}$$

Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 16 with 5. Write the result 80 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times9}16\\\underline{\times\phantom{9}45}\\\phantom{\times9}80\\\end{array}$$

Now multiply the first number with the 2^{nd} digit in 2^{nd} number to get intermediate results. That is Multiply 16 with 4. Write the result 64 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times9}16\\\underline{\times\phantom{9}45}\\\phantom{\times9}80\\\underline{\phantom{\times}64\phantom{9}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times9}16\\\underline{\times\phantom{9}45}\\\phantom{\times9}80\\\underline{\phantom{\times}64\phantom{9}}\\\phantom{\times}720\end{array}$$

Factor

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