1.) what is the prime factorization of 57

2.) what is the prime factorization of 54

1.
57= 3*19
Because 3 and 19 are both prime, that is the prime factorization.
Final 3*19

2.
54= 2*27
2 is prime but 27 can still be factored.
54=2*3*9
Again, 9 can still be factored.
54=2*3*3*3
2 and 3 cannot be further factored so that is the prime factorization.
Final 2*3*3*3
