Question

Question will be on the description. What would be the easiest way on doing this problem?
@Mertsj

Answer 1

22

Answer 2

The easiest way is to remember that 2 is the only even prime so the one whose only even factor is 2 would be the correct choice.

Answer 3

Can you explain by what you mean with "so the one whose only even factor is 2"?

Answer 4

Look at the first answer choice. It is 16. The factors of 16 are 2, 4, 8, and 16
All of those factors are even and only 2 is a prime number. So it couldn't be 16

Answer 5

Can you explain by using the example of 22? @Mertsj

Answer 6

The factors of 22 are 2 x 11
Both of those are prime numbers

Answer 7

Thank you.
