The Prime Factors are: 2, 3, 5
A factor of a composite number need not be a prime number, some factors are themselves composite. Prime factorisation is continuing to factorise each factor unless it is a prime. For example, start with 30. 6 goes into 30 so finding a factor is satisfied by simply identifying 6 as a factor of 30. Now 30 = 5*6 where 5 is a prime, but 6 is not so we need to factorise 6. 6 = 2*3 and therefore, 30 = 5*2*3 = 2*3*5 The last is the prime factorisation of 30.
13 is a prime number. The only prime factor of a prime number is the number itself.
That's a prime factor.
