All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor tree can help you visualize this.
Example: 210
210 Divide by two.
105,2 Divide by three.
35,3,2 Divide by five.
7,5,3,2 Stop. All the factors are prime.
2 x 3 x 5 x 7 = 210
That's the prime factorization of 210.

Prime factorization is the process of determining all of the prime factors of a given number. Prime factors are the prime numbers that when multiplied together give you the number to be factored. For example the prime factorization of 30 is 15 x 2
When all the factors are prime numbers, that's a prime factorization.
