So prime factorization is is finding which prime numbers multiply together to make the original number.
So 48 can be spilt up into 8,6
6-3 and 2 which are prime numbers
8 can be spilt into 4 and 2. 4 isn’t but 2 is
4-2 and 2
So 2*2*2*2*3 is the prime factorization
I hope I helped please ask any questions in the comments
