PRIME FACTORIZATION

__Rules of Prime Factorization __

**If the number is even
then take out the factor 2**

**If the sum of digit
in the number obtained after step 1 is a multiple of 3, so we will take the
factor 3. We have to continue this step as long as the number is a multiple of
three.**

**If the last digit in
the number obtained after step 2 is 5, take out the factor 5.**

**Try by division to
take out prime factors like 7, 11, 13 and 17**

__Example
– __

**1)
360 = 2 X 180 **

**
= 2 X 2 X 90**

**
= 2 X 2 X 2 X 45**

**
= 2 X 2 X 2 X 3 X 15**

**
= 2 X 2 X 2 X 3 X 3 X 5**

**
= 2****ᶟ**** X 3² X ****5¹ **
