Factor  
Factors are numbers you can multiply together to get another number:
Example: 2 and 3 are factors of 6, because 2 × 3 = 6. 
Multiple  more ...  
The result of multiplying a number by an integer (not a fraction).
Examples: 12 is a multiple of 3, because 3 × 4 = 12 6 is a multiple of 3, because 3 × 2 = 6 But 7 is NOT a multiple of 3 Index Notation
(Note: Index and Power mean the same things as Exponent)
Example: 10^{3} = 10 × 10 × 10 = 1,000
Example: 10^{4} = 10 × 10 × 10 × 10 = 10,000

Prime Factorization
"Prime Factorization" is finding which prime numbers multiply together to make the original number.
Here are some examples:
Example 1: What are the prime factors of 12 ?
It is best to start working from the smallest prime number, which is 2, so let's check:
12 ÷ 2 = 6
Yes, it divided evenly by 2. We have taken the first step!
But 6 is not a prime number, so we need to go further. Let's try 2 again:
6 ÷ 2 = 3
Yes, that worked also. And 3 is a prime number, so we have the answer:
12 = 2 × 2 × 3
As you can see, every factor is a prime number, so the answer must be right.
Note: 12 = 2 × 2 × 3 can also be written using exponents as 12 = 2^{2} × 3
You forgot to write the source but the information is reliable and accurate.
