Math : Prime Factorization

Factors

 Factors are the number we multiply together to get another number.

Example

 3*4=12

3 and 4 are the factors of 12

Prime number

 A whole number which has exactly two factor that is 1 and the number itself.

2,3,5,7...are some of the prime numbers.

Prime factorization

 A prime factorization is finding which prime numbers multiply together to get the original number

Example

12 = 4*3=6*2=2*3*2

In the above example, 4 and 6 are not prime numbers.
In, 12=2*3*2 where 2,3,2 are prime numbers.
Hence the prime factors of 12 is 2 , 3 , 2.
