Question

Write all the factors of $999$ ?

Answer 1

Factor: A Factor of a number is an exact divisor of that number.

The given number is $999$

Here,

$$\begin{gathered} \mathrm{999\; ÷\; 1\; =\; 999,} \\ \mathrm{999\; ÷\; 3\; =\; 333,} \\ \mathrm{999\; ÷\; 9\; =\; 111,} \\ \mathrm{999\; ÷\; 27\; =\; 37,} \\ \mathrm{999\; ÷\; 37\; =\; 27,} \\ \mathrm{999\; ÷\; 111\; =\; 9,} \\ \mathrm{999\; ÷\; 333\; =\; 3,} \\ \mathrm{999\; ÷\; 999\; =\; 1} \end{gathered}$$

Clearly, $999$ is exactly divisible by $1,3,9,27,37,111,333,999$

Hence, all the factors of $999$ are $1,3,9,27,37,111,333,999$
