Prime factorization of $$$1924$$$
Your Input
Find the prime factorization of $$$1924$$$.
Solution
Start with the number $$$2$$$.
Determine whether $$$1924$$$ is divisible by $$$2$$$.
It is divisible, thus, divide $$$1924$$$ by $$${\color{green}2}$$$: $$$\frac{1924}{2} = {\color{red}962}$$$.
Determine whether $$$962$$$ is divisible by $$$2$$$.
It is divisible, thus, divide $$$962$$$ by $$${\color{green}2}$$$: $$$\frac{962}{2} = {\color{red}481}$$$.
Determine whether $$$481$$$ is divisible by $$$2$$$.
Since it is not divisible, move to the next prime number.
The next prime number is $$$3$$$.
Determine whether $$$481$$$ is divisible by $$$3$$$.
Since it is not divisible, move to the next prime number.
The next prime number is $$$5$$$.
Determine whether $$$481$$$ is divisible by $$$5$$$.
Since it is not divisible, move to the next prime number.
The next prime number is $$$7$$$.
Determine whether $$$481$$$ is divisible by $$$7$$$.
Since it is not divisible, move to the next prime number.
The next prime number is $$$11$$$.
Determine whether $$$481$$$ is divisible by $$$11$$$.
Since it is not divisible, move to the next prime number.
The next prime number is $$$13$$$.
Determine whether $$$481$$$ is divisible by $$$13$$$.
It is divisible, thus, divide $$$481$$$ by $$${\color{green}13}$$$: $$$\frac{481}{13} = {\color{red}37}$$$.
The prime number $$${\color{green}37}$$$ has no other factors then $$$1$$$ and $$${\color{green}37}$$$: $$$\frac{37}{37} = {\color{red}1}$$$.
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: $$$1924 = 2^{2} \cdot 13 \cdot 37$$$.
Answer
The prime factorization is $$$1924 = 2^{2} \cdot 13 \cdot 37$$$A.
