Solve 21*47

$$21 \times 47$$

Evaluate

$$987$$

Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times9}21\\\underline{\times\phantom{9}47}\\\end{array}$$

Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 21 with 7. Write the result 147 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times9}21\\\underline{\times\phantom{9}47}\\\phantom{\times}147\\\end{array}$$

Now multiply the first number with the 2^{nd} digit in 2^{nd} number to get intermediate results. That is Multiply 21 with 4. Write the result 84 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times9}21\\\underline{\times\phantom{9}47}\\\phantom{\times}147\\\underline{\phantom{\times}84\phantom{9}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times9}21\\\underline{\times\phantom{9}47}\\\phantom{\times}147\\\underline{\phantom{\times}84\phantom{9}}\\\phantom{\times}987\end{array}$$

Factor

$$3\times 7\times 47$$
