The prime factorization of a number uses only primes.
Ex: The prime factorization of 12 is not 6 x 2, and not 4 x 3, because 6 and 4 are not prime numbers. The prime factorization is 2 x 2 x 3. Their product is 12 and all factors are prime numbers.
To get a prime factorization you are usually taught to factor through division by small prime numbers, sometimes you must use the same number more than once as in the example of 12 above 2 was used twice.
Ex: find the prime factorization of 18.
The smallest prime is 2... divide by 2
18 / 2 = 9 .... for the next step divide 9 by a prime
9 / 3 = 3 ... this is a prme ... it is also a factor
so the prime factorization is 18 = 2x3x3
Ex. find the prime factorization of 35.
35 cannot be divided by 2, or 3, so use 5 first
35 / 5 = 7 .... since 7 is a prime we are finished.
The prime factorization of 35 is
35 = 5 x 7
Some teachers teach this using a "factor tree" .. I can't type one of those on a computer.

The prime factorization of 10 is 2 x 5. The prime factorization of 100 is 2^2 x 5^2. The prime factorization of 1000 is 2^3 x 5^3.
How do you factor monomials?
All you do is write the prime factorization. I'll do an example: 50y First, you find the prime factorization of the coefficent using a factor tree, but it won't let me do that, so this is what the prime factorization should look like: 2x5x5 Then you add the variable: 2x5x5xy When you have a negative coefficent, just put a negative one in front of your answer. -50y = -1x2x5x5xy
