Question

Write the given set in Roster form and also in Set-Builder Form:

(a) Set of all-natural ​number that can ​divide $24$ completely.

Answer 1

Step: Writing the given set in Roster form and also in Set-Builder Form.
Natural numbers that divide $24$ are the factors of 24 which are $1,2,3,4,6,8,12,24.$
Hence, the required Roster form is:
$\{1,2,3,4,6,8,12,24\}$

The Set builder form is:
$\left\{\text{x : x is natural number which divides 24 completely}\right\}.$
