Question

Which is a true statement about the number 1?

One is a factor of every whole number since every number is divisible by itself.
One is not a factor of any number because it is neither a prime number nor a composite number.
One is a prime number because it has less than two factors.
One is a composite number because it has more than two factors.

Answer 1

answer is: One is a factor of every whole number since every number is divisible by itself.

Answer 2

The correct answer is One is a factor of every whole number since every number is divisible by itself.

Explanation:

A factor is that number that divides another number evenly, with no remainder. That is why the number 1 is a factor of every whole number since every number is divisible by itself.

On the other hand, the number 1 is not a prime number since it cannot be divided by two factors.

It is also not a composite number since it does not have two smaller positive integers.

Therefore, the correct answer is One is a factor of every whole number since every number is divisible by itself.
