How could you find the number with the prime factorization of 2x2 x 3x3?
To find the original number when given the prime factors, we have to work backwards. First, we simplify into 2 squared times 3 squared. (2x2) x (3x3) Then we expand the brackets. 4 x 9 = 54 Therefore 54 is the number, with 2x2 and 3x3 as the prime factors.

Prime factorization is when you find all the prime factors of a number.
How can numbers be prime?
A prime number is any number that only has one and itself as factors. Therefore, to tell if a number is prime simply find it's factors. If it has more than two factors than it is not a prime number.
How do you test a number to see if it is a prime number?
A prime number is any number that only has one and itself as factors. Therefore, to tell if a number is prime simply find it's factors. If it has more than two factors than it is not a prime number.
