Prime factorization of $$$2471$$$

Find the prime factorization of $$$2471$$$.

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

Determine whether $$$2471$$$ is divisible by $$$2$$$.

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

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

Determine whether $$$2471$$$ is divisible by $$$3$$$.

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

The next prime number is $$$5$$$.

Determine whether $$$2471$$$ is divisible by $$$5$$$.

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

The next prime number is $$$7$$$.

Determine whether $$$2471$$$ is divisible by $$$7$$$.

It is divisible, thus, divide $$$2471$$$ by $$${\color{green}7}$$$: $$$\frac{2471}{7} = {\color{red}353}$$$.

The prime number $$${\color{green}353}$$$ has no other factors then $$$1$$$ and $$${\color{green}353}$$$: $$$\frac{353}{353} = {\color{red}1}$$$.

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: $$$2471 = 7 \cdot 353$$$.

The prime factorization is $$$2471 = 7 \cdot 353$$$A.
