Explanation of number 405 Prime Factorization

Prime Factorization of 405 it is expressing 405 as the product of prime factors. In other words it is finding which prime numbers should be multiplied together to make 405.

Since number 405 is a Composite number (not Prime) we can do its Prime Factorization.

To get a list of all Prime Factors of 405, we have to iteratively divide 405 by the smallest prime number possible until the result equals 1.

Here is the complete solution of finding Prime Factors of 405:

The smallest Prime Number which can divide 405 without a remainder is 3. So the first calculation step would look like:

405 ÷ 3 = 135

Now we repeat this action until the result equals 1:

135 ÷ 3 = 45

45 ÷ 3 = 15

15 ÷ 3 = 5

5 ÷ 5 = 1

Now we have all the Prime Factors for number 405. It is: 3, 3, 3, 3, 5

Or you may also write it in exponential form: 34 × 5
