Find the prime factorization of $1359$.

### Solution

Start with the number $2$.

Determine whether $1359$ is divisible by $2$.

Since it is not divisible, move to the next prime number.

The next prime number is $3$.

Determine whether $1359$ is divisible by $3$.

It is divisible, thus, divide $1359$ by ${\color{green}3}$: $\frac{1359}{3} = {\color{red}453}$.

Determine whether $453$ is divisible by $3$.

It is divisible, thus, divide $453$ by ${\color{green}3}$: $\frac{453}{3} = {\color{red}151}$.

The prime number ${\color{green}151}$ has no other factors then $1$ and ${\color{green}151}$: $\frac{151}{151} = {\color{red}1}$.

Since we have obtained $1$, we are done.

Now, just count the number of occurences of the divisors (green numbers), and write down the prime factorization: $1359 = 3^{2} \cdot 151$.

The prime factorization is $1359 = 3^{2} \cdot 151$A.
