Which number is a prime number? 2 9 24 39 which is the correct number?

jimthompson5910 (jim_thompson5910):

which one do you think it is

jimthompson5910 (jim_thompson5910):

Remember that a prime number only has factors of 1 and itself

OpenStudy (anonymous):

maybe.,,,, i think i is 24?

jimthompson5910 (jim_thompson5910):

So for instance, because 9 has the factors 1, 3, 9, it is NOT prime

jimthompson5910 (jim_thompson5910):

24 has the factors 1, 2, 3, 4, 6, 8, 12, 24, so it is NOT prime

OpenStudy (anonymous):

so then its 39?

jimthompson5910 (jim_thompson5910):

does 2 go into 39?

OpenStudy (anonymous):

2
