Prime factorization of $$$4864$$$
Your Input
Find the prime factorization of $$$4864$$$.
Solution
Start with the number $$$2$$$.
Determine whether $$$4864$$$ is divisible by $$$2$$$.
It is divisible, thus, divide $$$4864$$$ by $$${\color{green}2}$$$: $$$\frac{4864}{2} = {\color{red}2432}$$$.
Determine whether $$$2432$$$ is divisible by $$$2$$$.
It is divisible, thus, divide $$$2432$$$ by $$${\color{green}2}$$$: $$$\frac{2432}{2} = {\color{red}1216}$$$.
Determine whether $$$1216$$$ is divisible by $$$2$$$.
It is divisible, thus, divide $$$1216$$$ by $$${\color{green}2}$$$: $$$\frac{1216}{2} = {\color{red}608}$$$.
Determine whether $$$608$$$ is divisible by $$$2$$$.
It is divisible, thus, divide $$$608$$$ by $$${\color{green}2}$$$: $$$\frac{608}{2} = {\color{red}304}$$$.
Determine whether $$$304$$$ is divisible by $$$2$$$.
It is divisible, thus, divide $$$304$$$ by $$${\color{green}2}$$$: $$$\frac{304}{2} = {\color{red}152}$$$.
Determine whether $$$152$$$ is divisible by $$$2$$$.
It is divisible, thus, divide $$$152$$$ by $$${\color{green}2}$$$: $$$\frac{152}{2} = {\color{red}76}$$$.
Determine whether $$$76$$$ is divisible by $$$2$$$.
It is divisible, thus, divide $$$76$$$ by $$${\color{green}2}$$$: $$$\frac{76}{2} = {\color{red}38}$$$.
Determine whether $$$38$$$ is divisible by $$$2$$$.
It is divisible, thus, divide $$$38$$$ by $$${\color{green}2}$$$: $$$\frac{38}{2} = {\color{red}19}$$$.
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: $$$4864 = 2^{8} \cdot 19$$$.
Answer
The prime factorization is $$$4864 = 2^{8} \cdot 19$$$A.
