Kia thinks that every number has at least two factors. Which explains whether Kia is correct?

Question

Kia is correct because prime numbers have two factors and composite numbers have more than two factors.
Kia is correct because composite numbers have two factors and prime numbers have more than two factors.
Kia is incorrect because prime numbers do not have any factors.
Kia is incorrect because the only factor of 1 is 1.

Answer 1

Kia is correct because prime numbers have two factors (1 and the number itself), and composite numbers have more than two factors. However, it is important to note that the number 1 has only one factor (itself), which means it does not meet the criteria of having at least two factors. Therefore, a more accurate expression of Kia's statement would clarify that not every number meets this criterion, specifically mentioning that 1 is an exception.

So, the most appropriate option from those provided is the first one:

Kia is correct because prime numbers have two factors and composite numbers have more than two factors.

But it's worth noting that while this statement holds true for most numbers, Kia's claim that "every number has at least two factors" is technically incorrect because the number 1 only has one factor.
