Question 1 • *WHS Pre-Algebra - MA3119 A-CR

Which is a true statement about the number 1?

Answer

A

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

B

One is not a factor of any number because it is neither a prime number nor a composite number.

C

One is a prime number because it has less than two factors.

D

One is a composite number because it has more than two factors.

Explanation

One is a factor of every whole number because every whole number can be divided by 1 with no remainder. For example, 8 ÷ 1 = 8. One is neither prime nor composite, but that does not stop it from being a factor; the reason given in choice A about a number being divisible by itself is true but does not explain why 1 is a factor of every number.
