What is prime factorization?

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

Finding the prime factors of 952,952

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 952,952 by 2

952,952 ÷ 2 = 476,476 - No remainder! 2 is one of the factors!
476,476 ÷ 2 = 238,238 - No remainder! 2 is one of the factors!
238,238 ÷ 2 = 119,119 - No remainder! 2 is one of the factors!
119,119 ÷ 2 = 59,559.5 - There is a remainder. We can't divide by 2 evenly anymore. Let's try the next prime number
119,119 ÷ 3 = 39,706.3333 - This has a remainder. 3 is not a factor.
119,119 ÷ 5 = 23,823.8 - This has a remainder. 5 is not a factor.
119,119 ÷ 7 = 17,017 - No remainder! 7 is one of the factors!
17,017 ÷ 7 = 2,431 - No remainder! 7 is one of the factors!
2,431 ÷ 7 = 347.2857 - There is a remainder. We can't divide by 7 evenly anymore. Let's try the next prime number
2,431 ÷ 11 = 221 - No remainder! 11 is one of the factors!
221 ÷ 11 = 20.0909 - There is a remainder. We can't divide by 11 evenly anymore. Let's try the next prime number
221 ÷ 13 = 17 - No remainder! 13 is one of the factors!
17 ÷ 13 = 1.3077 - There is a remainder. We can't divide by 13 evenly anymore. Let's try the next prime number
17 ÷ 17 = 1 - No remainder! 17 is one of the factors!

The orange divisor(s) above are the prime factors of the number 952,952. If we put all of it together we have the factors 2 x 2 x 2 x 7 x 7 x 11 x 13 x 17 = 952,952. It can also be written in exponential form as 23 x 72 x 111 x 131 x 171.
