Prime Factorization

30 Prime factorization of 30
/ \ = 2 x 3 x 5
2 15
/ \ Notice that 2,3,5 are all prime numbers.
3 5 That is why it is called prime factorization.

there are generally 2 methods,of finding prime factorization of a number

1.Prime Factorization Tree
(as shown earlier)
2.Repeated Division
2/30
3/15
5 30=2x3x5
INDEX NOTATION

express 2x2x2x7x7 in index notation
2x2x2x7x7=2 to the power of 3 X7 to the power of 2.(index notation)
