Prime factorization of $$$1232$$$

Find the prime factorization of $$$1232$$$.

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

Determine whether $$$1232$$$ is divisible by $$$2$$$.

It is divisible, thus, divide $$$1232$$$ by $$${\color{green}2}$$$: $$$\frac{1232}{2} = {\color{red}616}$$$.

Determine whether $$$616$$$ is divisible by $$$2$$$.

It is divisible, thus, divide $$$616$$$ by $$${\color{green}2}$$$: $$$\frac{616}{2} = {\color{red}308}$$$.

Determine whether $$$308$$$ is divisible by $$$2$$$.

It is divisible, thus, divide $$$308$$$ by $$${\color{green}2}$$$: $$$\frac{308}{2} = {\color{red}154}$$$.

Determine whether $$$154$$$ is divisible by $$$2$$$.

It is divisible, thus, divide $$$154$$$ by $$${\color{green}2}$$$: $$$\frac{154}{2} = {\color{red}77}$$$.

Determine whether $$$77$$$ is divisible by $$$2$$$.

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

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

Determine whether $$$77$$$ is divisible by $$$3$$$.

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

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

Determine whether $$$77$$$ is divisible by $$$5$$$.

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

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

Determine whether $$$77$$$ is divisible by $$$7$$$.

It is divisible, thus, divide $$$77$$$ by $$${\color{green}7}$$$: $$$\frac{77}{7} = {\color{red}11}$$$.

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: $$$1232 = 2^{4} \cdot 7 \cdot 11$$$.

The prime factorization is $$$1232 = 2^{4} \cdot 7 \cdot 11$$$A.
