Write the following sets in roster form :
$D = \{ x:x$ is a prime number which is divisor of $60\} $
Write the following sets in roster form :
$D = \{ x:x$ is a prime number which is divisor of $60\} $
$D = \{ x:x$ is a prime number which is divisor of $60\} $
| $2$ | $60$ |
| $2$ | $30$ |
| $3$ | $15$ |
| $5$ |
$\therefore 60=2 \times 2 \times 3 \times 5$
The elements of this set are $2,3$ and $5$ only.
Therefore, this set can be written in roster form as $D=\{2,3,5\}$
