Question

Write the factors of the following number and decide if the number is prime or composite:

$30$

Answer 1

Given number: $30$

A composite number is a number which has at least one factor other than $1$ and itself.

We know that all the numbers that divide a number completely, i.e., without leaving any remainder are called factors of that number.

Here, factors of $30$: $1,2,3,5,6,10,15,30.$

And also $30$ has a factors other than $1$ and itself.

Hence, $30$ is a composite number.
