Prime factorization of $$$3192$$$
Your Input
Find the prime factorization of $$$3192$$$.
Solution
Start with the number $$$2$$$.
Determine whether $$$3192$$$ is divisible by $$$2$$$.
It is divisible, thus, divide $$$3192$$$ by $$${\color{green}2}$$$: $$$\frac{3192}{2} = {\color{red}1596}$$$.
Determine whether $$$1596$$$ is divisible by $$$2$$$.
It is divisible, thus, divide $$$1596$$$ by $$${\color{green}2}$$$: $$$\frac{1596}{2} = {\color{red}798}$$$.
Determine whether $$$798$$$ is divisible by $$$2$$$.
It is divisible, thus, divide $$$798$$$ by $$${\color{green}2}$$$: $$$\frac{798}{2} = {\color{red}399}$$$.
Determine whether $$$399$$$ is divisible by $$$2$$$.
Since it is not divisible, move to the next prime number.
The next prime number is $$$3$$$.
Determine whether $$$399$$$ is divisible by $$$3$$$.
It is divisible, thus, divide $$$399$$$ by $$${\color{green}3}$$$: $$$\frac{399}{3} = {\color{red}133}$$$.
Determine whether $$$133$$$ is divisible by $$$3$$$.
Since it is not divisible, move to the next prime number.
The next prime number is $$$5$$$.
Determine whether $$$133$$$ is divisible by $$$5$$$.
Since it is not divisible, move to the next prime number.
The next prime number is $$$7$$$.
Determine whether $$$133$$$ is divisible by $$$7$$$.
It is divisible, thus, divide $$$133$$$ by $$${\color{green}7}$$$: $$$\frac{133}{7} = {\color{red}19}$$$.
The prime number $$${\color{green}19}$$$ has no other factors then $$$1$$$ and $$${\color{green}19}$$$: $$$\frac{19}{19} = {\color{red}1}$$$.
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: $$$3192 = 2^{3} \cdot 3 \cdot 7 \cdot 19$$$.
Answer
The prime factorization is $$$3192 = 2^{3} \cdot 3 \cdot 7 \cdot 19$$$A.
