Prime factorization of $$$3895$$$

Find the prime factorization of $$$3895$$$.

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

Determine whether $$$3895$$$ is divisible by $$$2$$$.

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

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

Determine whether $$$3895$$$ is divisible by $$$3$$$.

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

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

Determine whether $$$3895$$$ is divisible by $$$5$$$.

It is divisible, thus, divide $$$3895$$$ by $$${\color{green}5}$$$: $$$\frac{3895}{5} = {\color{red}779}$$$.

Determine whether $$$779$$$ is divisible by $$$5$$$.

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

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

Determine whether $$$779$$$ is divisible by $$$7$$$.

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

The next prime number is $$$11$$$.

Determine whether $$$779$$$ is divisible by $$$11$$$.

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

The next prime number is $$$13$$$.

Determine whether $$$779$$$ is divisible by $$$13$$$.

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

The next prime number is $$$17$$$.

Determine whether $$$779$$$ is divisible by $$$17$$$.

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

The next prime number is $$$19$$$.

Determine whether $$$779$$$ is divisible by $$$19$$$.

It is divisible, thus, divide $$$779$$$ by $$${\color{green}19}$$$: $$$\frac{779}{19} = {\color{red}41}$$$.

The prime number $$${\color{green}41}$$$ has no other factors then $$$1$$$ and $$${\color{green}41}$$$: $$$\frac{41}{41} = {\color{red}1}$$$.

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: $$$3895 = 5 \cdot 19 \cdot 41$$$.

The prime factorization is $$$3895 = 5 \cdot 19 \cdot 41$$$A.
