Prime factorization of $$$2700$$$
Your Input
Find the prime factorization of $$$2700$$$.
Solution
Start with the number $$$2$$$.
Determine whether $$$2700$$$ is divisible by $$$2$$$.
It is divisible, thus, divide $$$2700$$$ by $$${\color{green}2}$$$: $$$\frac{2700}{2} = {\color{red}1350}$$$.
Determine whether $$$1350$$$ is divisible by $$$2$$$.
It is divisible, thus, divide $$$1350$$$ by $$${\color{green}2}$$$: $$$\frac{1350}{2} = {\color{red}675}$$$.
Determine whether $$$675$$$ is divisible by $$$2$$$.
Since it is not divisible, move to the next prime number.
The next prime number is $$$3$$$.
Determine whether $$$675$$$ is divisible by $$$3$$$.
It is divisible, thus, divide $$$675$$$ by $$${\color{green}3}$$$: $$$\frac{675}{3} = {\color{red}225}$$$.
Determine whether $$$225$$$ is divisible by $$$3$$$.
It is divisible, thus, divide $$$225$$$ by $$${\color{green}3}$$$: $$$\frac{225}{3} = {\color{red}75}$$$.
Determine whether $$$75$$$ is divisible by $$$3$$$.
It is divisible, thus, divide $$$75$$$ by $$${\color{green}3}$$$: $$$\frac{75}{3} = {\color{red}25}$$$.
Determine whether $$$25$$$ is divisible by $$$3$$$.
Since it is not divisible, move to the next prime number.
The next prime number is $$$5$$$.
Determine whether $$$25$$$ is divisible by $$$5$$$.
It is divisible, thus, divide $$$25$$$ by $$${\color{green}5}$$$: $$$\frac{25}{5} = {\color{red}5}$$$.
The prime number $$${\color{green}5}$$$ has no other factors then $$$1$$$ and $$${\color{green}5}$$$: $$$\frac{5}{5} = {\color{red}1}$$$.
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: $$$2700 = 2^{2} \cdot 3^{3} \cdot 5^{2}$$$.
Answer
The prime factorization is $$$2700 = 2^{2} \cdot 3^{3} \cdot 5^{2}$$$A.
