Division Method:

 Step1: First we divide the  Example:
number by the smallest prime
number which divides the
number exactly.

 Step2: We divide the quotient
again by the smallest or the
next smallest prime number if

it is not exactly divisible by the
smallest prime number.
 We repeat the process again

and again till the quotient
becomes 1.

 Remember, we use only prime
numbers to divide.
 Step3: We multiply all the
prime factors. Remember, the

product is the number itself.
 Prime factorization of 216=

2x2x2x3x3x3
