Prime factorization of $$$724$$$
Your Input
Find the prime factorization of $$$724$$$.
Solution
Start with the number $$$2$$$.
Determine whether $$$724$$$ is divisible by $$$2$$$.
It is divisible, thus, divide $$$724$$$ by $$${\color{green}2}$$$: $$$\frac{724}{2} = {\color{red}362}$$$.
Determine whether $$$362$$$ is divisible by $$$2$$$.
It is divisible, thus, divide $$$362$$$ by $$${\color{green}2}$$$: $$$\frac{362}{2} = {\color{red}181}$$$.
The prime number $$${\color{green}181}$$$ has no other factors then $$$1$$$ and $$${\color{green}181}$$$: $$$\frac{181}{181} = {\color{red}1}$$$.
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: $$$724 = 2^{2} \cdot 181$$$.
Answer
The prime factorization is $$$724 = 2^{2} \cdot 181$$$A.
