Find the prime factorization of $4455$.

### Solution

Start with the number $2$.

Determine whether $4455$ is divisible by $2$.

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

The next prime number is $3$.

Determine whether $4455$ is divisible by $3$.

It is divisible, thus, divide $4455$ by ${\color{green}3}$: $\frac{4455}{3} = {\color{red}1485}$.

Determine whether $1485$ is divisible by $3$.

It is divisible, thus, divide $1485$ by ${\color{green}3}$: $\frac{1485}{3} = {\color{red}495}$.

Determine whether $495$ is divisible by $3$.

It is divisible, thus, divide $495$ by ${\color{green}3}$: $\frac{495}{3} = {\color{red}165}$.

Determine whether $165$ is divisible by $3$.

It is divisible, thus, divide $165$ by ${\color{green}3}$: $\frac{165}{3} = {\color{red}55}$.

Determine whether $55$ is divisible by $3$.

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

The next prime number is $5$.

Determine whether $55$ is divisible by $5$.

It is divisible, thus, divide $55$ by ${\color{green}5}$: $\frac{55}{5} = {\color{red}11}$.

The prime number ${\color{green}11}$ has no other factors then $1$ and ${\color{green}11}$: $\frac{11}{11} = {\color{red}1}$.

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: $4455 = 3^{4} \cdot 5 \cdot 11$.

The prime factorization is $4455 = 3^{4} \cdot 5 \cdot 11$A.
