We know that
But, can we write
12
as the product of just prime
numbers?
Well,
3
is a prime number, but
4
isn't.
Can we break
4
into a product of primes?

When we write a number as the
product of primes, it's called a
prime factorization.
Smaller numbers are pretty easy to
do... You just start with your times tables numbers ( like I
did with 12
):
Find the prime factorization of
18:
From our times tables
3
is prime, but we need to break the
6
up!
It's polite to put the factors in
order from least to greatest:
Here it is with exponents:
