- The prime factors are: 3 x 5 x 7 x 31
- or also written as { 3, 5, 7, 31 }

- Written in exponential form: 3
^{1}x 5^{1}x 7^{1}x 31^{1}

A:

- The prime factors are: 3 x 5 x 7 x 31

^{1}x 5^{1}x 7^{1}x 31^{1}

**Prime factorization** or **prime factor decomposition** is the process of finding which prime numbers can be multiplied together to make the original number.

To find the prime factors, you start by dividing the number by the first prime number, which is 2. If there
**is not** a remainder, meaning you can divide evenly, then 2 is a factor of the number. Continue dividing by 2 until you cannot divide evenly anymore. Write down how many 2's you were able to divide by evenly.
Now try dividing by the next prime factor, which is 3. The goal is to get to a quotient of 1.

Here are the first several prime factors: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29...

Let's start by dividing 3,255 by 2

3,255 ÷ 2 = 1,627.5 - This has a remainder. Let's try another prime number.

3,255 ÷ 3 = 1,085 - No remainder! 3 is one of the factors!

1,085 ÷ 3 = 361.6667 - There is a remainder. We can't divide by 3 evenly anymore. Let's try the next prime number

1,085 ÷ 5 = 217 - No remainder! 5 is one of the factors!

217 ÷ 5 = 43.4 - There is a remainder. We can't divide by 5 evenly anymore. Let's try the next prime number

217 ÷ 7 = 31 - No remainder! 7 is one of the factors!

31 ÷ 7 = 4.4286 - There is a remainder. We can't divide by 7 evenly anymore. Let's try the next prime number

31 ÷ 11 = 2.8182 - This has a remainder. 11 is not a factor.

31 ÷ 13 = 2.3846 - This has a remainder. 13 is not a factor.

31 ÷ 17 = 1.8235 - This has a remainder. 17 is not a factor.

...**Keep trying increasingly larger numbers until you find one that divides evenly.**

...

31 ÷ 31 = 1 - No remainder! 31 is one of the factors!

The orange divisor(s) above are the prime factors of the number 3,255. If we put all of it together we have the factors 3 x 5 x 7 x 31 = 3,255. It can also be written in exponential form as 3^{1} x 5^{1} x 7^{1} x 31^{1}.

Another way to do prime factorization is to use a factor tree. Below is a factor tree for the number 3,255.
