Another way to see if a number is prime is to count the number of factors. For example,
the number 4 has 2 factors, [ 2 4 ] the number 16 has 4 factors, [ 2 4 8 16 ] the number 7 has 1 factor, [ 7 ]
Thus, if a number has only one factor, it is prime. We ignore the factor 1 as it is trivial.
Your function should create a vector containing all the factors of any number x.
