Answer:
Prime no.
Step-by-step explanation:
<em>A number that only has two factors [</em><em> 1 </em><em>and </em><em>itself</em><em>] is called a prime no.</em>
For ex:
The factors of 2 are: 1,2
The factors of 3 is : 1,3
<em>But if you look at the factors of 6, there are; 1,2,3,6 [ 4 FACTORS]</em>
<u>Thus, 6 is a composite no. [Has more than 2 factors]</u>
