Prime factorization of $$$3094$$$
Your Input
Find the prime factorization of $$$3094$$$.
Solution
Start with the number $$$2$$$.
Determine whether $$$3094$$$ is divisible by $$$2$$$.
It is divisible, thus, divide $$$3094$$$ by $$${\color{green}2}$$$: $$$\frac{3094}{2} = {\color{red}1547}$$$.
Determine whether $$$1547$$$ is divisible by $$$2$$$.
Since it is not divisible, move to the next prime number.
The next prime number is $$$3$$$.
Determine whether $$$1547$$$ is divisible by $$$3$$$.
Since it is not divisible, move to the next prime number.
The next prime number is $$$5$$$.
Determine whether $$$1547$$$ is divisible by $$$5$$$.
Since it is not divisible, move to the next prime number.
The next prime number is $$$7$$$.
Determine whether $$$1547$$$ is divisible by $$$7$$$.
It is divisible, thus, divide $$$1547$$$ by $$${\color{green}7}$$$: $$$\frac{1547}{7} = {\color{red}221}$$$.
Determine whether $$$221$$$ is divisible by $$$7$$$.
Since it is not divisible, move to the next prime number.
The next prime number is $$$11$$$.
Determine whether $$$221$$$ is divisible by $$$11$$$.
Since it is not divisible, move to the next prime number.
The next prime number is $$$13$$$.
Determine whether $$$221$$$ is divisible by $$$13$$$.
It is divisible, thus, divide $$$221$$$ by $$${\color{green}13}$$$: $$$\frac{221}{13} = {\color{red}17}$$$.
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: $$$3094 = 2 \cdot 7 \cdot 13 \cdot 17$$$.
Answer
The prime factorization is $$$3094 = 2 \cdot 7 \cdot 13 \cdot 17$$$A.
