24 is a possible answer, because one of its factors is 3, it is not a square
number. One more than 24 is 25 which is a square number, and 1 less than 24
is 23, which is a prime number.
48 is a possible answer, because one of its factors is 3, it is not a square
number. One more than 48 is 49 which is a square number, and 1 less than 48
is 47, which is a prime number.
168 is a possible answer, because one of its factors is 3, it is not a square
number. One more than 168 is 169 which is a square number, and 1 less than 168
is 167, which is a prime number.
So there are lots and lots of possible answers.
