Prime factorization of $$$2992$$$

Find the prime factorization of $$$2992$$$.

Start with the number $$$2$$$.

Determine whether $$$2992$$$ is divisible by $$$2$$$.

It is divisible, thus, divide $$$2992$$$ by $$${\color{green}2}$$$: $$$\frac{2992}{2} = {\color{red}1496}$$$.

Determine whether $$$1496$$$ is divisible by $$$2$$$.

It is divisible, thus, divide $$$1496$$$ by $$${\color{green}2}$$$: $$$\frac{1496}{2} = {\color{red}748}$$$.

Determine whether $$$748$$$ is divisible by $$$2$$$.

It is divisible, thus, divide $$$748$$$ by $$${\color{green}2}$$$: $$$\frac{748}{2} = {\color{red}374}$$$.

Determine whether $$$374$$$ is divisible by $$$2$$$.

It is divisible, thus, divide $$$374$$$ by $$${\color{green}2}$$$: $$$\frac{374}{2} = {\color{red}187}$$$.

Determine whether $$$187$$$ is divisible by $$$2$$$.

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

The next prime number is $$$3$$$.

Determine whether $$$187$$$ is divisible by $$$3$$$.

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

The next prime number is $$$5$$$.

Determine whether $$$187$$$ is divisible by $$$5$$$.

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

The next prime number is $$$7$$$.

Determine whether $$$187$$$ is divisible by $$$7$$$.

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

The next prime number is $$$11$$$.

Determine whether $$$187$$$ is divisible by $$$11$$$.

It is divisible, thus, divide $$$187$$$ by $$${\color{green}11}$$$: $$$\frac{187}{11} = {\color{red}17}$$$.

The prime number $$${\color{green}17}$$$ has no other factors then $$$1$$$ and $$${\color{green}17}$$$: $$$\frac{17}{17} = {\color{red}1}$$$.

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: $$$2992 = 2^{4} \cdot 11 \cdot 17$$$.

The prime factorization is $$$2992 = 2^{4} \cdot 11 \cdot 17$$$A.
