yes, you are correct: 5*3 = 15, 15*2 = 30, and 5,3,2 are all primes.

Yes you are correct
5*5= 25*2 = 50. that one cant be.
10 is simplified to more factors so a is also incorrect.
6 is also simplified into more fators.
the only choice where there are only prime numbers is
5,3,2. 5*3= 15*2 = 30. you are right.

30 = 10 x 3 = 2 x 5 x 3
Thes are prime numbers and this agrees with your answer of 5 , 3 , 2

yes, you are correct: 5*3 = 15, 15*2 = 30, and 5,3,2 are all primes.
so you are of course correct
and you got it

Yes.
The next primes are 7, 11, 13, none of which divide 30 evenly.
(actually, you never have to check past the square root of the number you are factoring. )
