can someone help me

OpenStudy (math&ing001):

Sure, do you know about prime numbers ?

OpenStudy (anonymous):

oh ok thanks

OpenStudy (math&ing001):

The easiest way to do it is to divide the number by prime numbers in order. You start by 2. Divide 144 by 2 until it's no longer possible like this|dw:1405700391521:dw| then you do the same with '3', then 5 ... Until you get it to a product of prime numbers in exponential form.

Let's continue, so 9 is no longer divisible by 2.|dw:1405700936422:dw|
