Do you know the definitions of factors? Factors are amount of different the numbers that can go into a number. Like let's take 27.
3*9=27
There is no more factors of 27. (a factor is not 1*27 or 1 times any number.)
A prime number (like 13) cannot have ANY factors because no even numbers go into it.
Please understand this and take this into consideration for your response
