Example Question #1 : Prime Numbers
Which of the following is the product of two distinct prime numbers?
There are two key terms in this question that we need to understand in order to answer the question correctly: product and prime numbers.
Product is the answer to a multiplication problem.
Prime numbers are numbers that are greater than and only have factors of the number
and itself. For example
is a prime number because it's greater than
and the factors of
are only
and
.
To find the correct answer, we need to know the factor pairs for our answer choices. The correct answer will have a factor pair of two prime numbers.
Let's look at our answer options:
- from our definition of a prime number we know that
cannot be correct because prime numbers are greater than
.
- A factor pair for
is
. Though
is a prime number,
is not.
- A factor pair for
is
, and
is not a prime number.
- A factor pair for
is
. Both
and
are prime numbers, thus
is our correct answer.
