Answer:

You (try to) divide your number by successive primes 2,3,5,7,11...

Step-by-step explanation:

Example :

Say you want to factor 756

Even number, divide by 2: 756=2⋅378

Even, divide by 2: 756=2⋅2⋅189

Odd, so try 3: 756=2⋅2⋅3⋅63

And again: 756=2⋅2⋅3⋅3⋅21

And again: 756=2⋅2⋅3⋅3⋅3⋅7

7 is a prime, so you're finished.

You write the result as 756=22⋅33⋅7
