Find the prime factorization of $$$2181$$$.


Start with the number $$$2$$$.

Determine whether $$$2181$$$ is divisible by $$$2$$$.

Since it is not divisible, move to the next prime number.

The next prime number is $$$3$$$.

Determine whether $$$2181$$$ is divisible by $$$3$$$.

It is divisible, thus, divide $$$2181$$$ by $$${\color{green}3}$$$: $$$\frac{2181}{3} = {\color{red}727}$$$.

The prime number $$${\color{green}727}$$$ has no other factors then $$$1$$$ and $$${\color{green}727}$$$: $$$\frac{727}{727} = {\color{red}1}$$$.

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: $$$2181 = 3 \cdot 727$$$.


The prime factorization is $$$2181 = 3 \cdot 727$$$A.
