Recall that to find the prime factorization of a number is to find prime numbers whose multiplication give us the initial number. For example, if we want to find the prime factorization of 10, we can see that 10=2*5 and 2 and 5 are prime numbers. Note that it is the same 2*5 or 5*2.
In this example, we have 48. We can right 48 = 8*6 or 48 =12*4. However, the prime factorization is unique. So, it doesn't matter if we start with 6 or with 12, since we will end up in the same factorization
