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.
It is itself because 31 is a prime number
prime factorization of 12: 2 x 2 x 3
32 = 25
2 x 2 x 13 = 52
As a product of its prime factors: 2*3*5*5 = 150 or as 2*3*52 = 150
Example: 210 210 105,2 35,3,2 7,5,3,2 2 x 3 x 5 x 7 = 210
