Find the prime factorization of $4816$.

### Solution

Start with the number $2$.

Determine whether $4816$ is divisible by $2$.

It is divisible, thus, divide $4816$ by ${\color{green}2}$: $\frac{4816}{2} = {\color{red}2408}$.

Determine whether $2408$ is divisible by $2$.

It is divisible, thus, divide $2408$ by ${\color{green}2}$: $\frac{2408}{2} = {\color{red}1204}$.

Determine whether $1204$ is divisible by $2$.

It is divisible, thus, divide $1204$ by ${\color{green}2}$: $\frac{1204}{2} = {\color{red}602}$.

Determine whether $602$ is divisible by $2$.

It is divisible, thus, divide $602$ by ${\color{green}2}$: $\frac{602}{2} = {\color{red}301}$.

Determine whether $301$ is divisible by $2$.

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

The next prime number is $3$.

Determine whether $301$ is divisible by $3$.

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

The next prime number is $5$.

Determine whether $301$ is divisible by $5$.

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

The next prime number is $7$.

Determine whether $301$ is divisible by $7$.

It is divisible, thus, divide $301$ by ${\color{green}7}$: $\frac{301}{7} = {\color{red}43}$.

The prime number ${\color{green}43}$ has no other factors then $1$ and ${\color{green}43}$: $\frac{43}{43} = {\color{red}1}$.

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: $4816 = 2^{4} \cdot 7 \cdot 43$.

The prime factorization is $4816 = 2^{4} \cdot 7 \cdot 43$A.
