Prime factorization of $$$4470$$$
Your Input
Find the prime factorization of $$$4470$$$.
Solution
Start with the number $$$2$$$.
Determine whether $$$4470$$$ is divisible by $$$2$$$.
It is divisible, thus, divide $$$4470$$$ by $$${\color{green}2}$$$: $$$\frac{4470}{2} = {\color{red}2235}$$$.
Determine whether $$$2235$$$ is divisible by $$$2$$$.
Since it is not divisible, move to the next prime number.
The next prime number is $$$3$$$.
Determine whether $$$2235$$$ is divisible by $$$3$$$.
It is divisible, thus, divide $$$2235$$$ by $$${\color{green}3}$$$: $$$\frac{2235}{3} = {\color{red}745}$$$.
Determine whether $$$745$$$ is divisible by $$$3$$$.
Since it is not divisible, move to the next prime number.
The next prime number is $$$5$$$.
Determine whether $$$745$$$ is divisible by $$$5$$$.
It is divisible, thus, divide $$$745$$$ by $$${\color{green}5}$$$: $$$\frac{745}{5} = {\color{red}149}$$$.
The prime number $$${\color{green}149}$$$ has no other factors then $$$1$$$ and $$${\color{green}149}$$$: $$$\frac{149}{149} = {\color{red}1}$$$.
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: $$$4470 = 2 \cdot 3 \cdot 5 \cdot 149$$$.
Answer
The prime factorization is $$$4470 = 2 \cdot 3 \cdot 5 \cdot 149$$$A.
