Prime factorization of $$$3768$$$
Your Input
Find the prime factorization of $$$3768$$$.
Solution
Start with the number $$$2$$$.
Determine whether $$$3768$$$ is divisible by $$$2$$$.
It is divisible, thus, divide $$$3768$$$ by $$${\color{green}2}$$$: $$$\frac{3768}{2} = {\color{red}1884}$$$.
Determine whether $$$1884$$$ is divisible by $$$2$$$.
It is divisible, thus, divide $$$1884$$$ by $$${\color{green}2}$$$: $$$\frac{1884}{2} = {\color{red}942}$$$.
Determine whether $$$942$$$ is divisible by $$$2$$$.
It is divisible, thus, divide $$$942$$$ by $$${\color{green}2}$$$: $$$\frac{942}{2} = {\color{red}471}$$$.
Determine whether $$$471$$$ is divisible by $$$2$$$.
Since it is not divisible, move to the next prime number.
The next prime number is $$$3$$$.
Determine whether $$$471$$$ is divisible by $$$3$$$.
It is divisible, thus, divide $$$471$$$ by $$${\color{green}3}$$$: $$$\frac{471}{3} = {\color{red}157}$$$.
The prime number $$${\color{green}157}$$$ has no other factors then $$$1$$$ and $$${\color{green}157}$$$: $$$\frac{157}{157} = {\color{red}1}$$$.
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: $$$3768 = 2^{3} \cdot 3 \cdot 157$$$.
Answer
The prime factorization is $$$3768 = 2^{3} \cdot 3 \cdot 157$$$A.
