The factors of 405 and the prime factors of 405 differ because four hundred and five is a composite number. Also, despite being closely related, the prime factors of 405 and the prime factorization of 405 are not exactly the same either. In any case, by reading on you can learn the answer to the question what are the factors of 405? and everything else you want to know about the topic.
What are the Factors of 405?
They are: 405, 135, 81, 45, 27, 15, 9, 5, 3, 1. These are all the factors of 405, and every entry in the list can divide 405 without rest (modulo 0). That’s why the terms factors and divisors of 405 can be used interchangeably.
As is the case for any natural number greater than zero, the number itself, here 405, as well as 1 are factors and divisors of 405.
Prime Factors of 405
The prime factors of 405 are the prime numbers which divide 405 exactly, without remainder as defined by the Euclidean division. In other words, a prime factor of 405 divides the number 405 without any rest, modulo 0.
For 405, the prime factors are: 3, 5. By definition, 1 is not a prime number.
Besides 1, what sets the factors and the prime factors of the number 405 apart is the word “prime”. The former list contains both, composite and prime numbers, whereas the latter includes only prime numbers.
Prime Factorization of 405
The prime factorization of 405 is 3 x 3 x 3 x 3 x 5. This is a unique list of the prime factors, along with their multiplicities. Note that the prime factorization of 405 does not include the number 1, yet it does include every instance of a certain prime factor.
405 is a composite number. In contrast to prime numbers which only have one factorization, composite numbers like 405 have at least two factorizations.
To illustrate what that means select the rightmost and leftmost integer in 405, 135, 81, 45, 27, 15, 9, 5, 3, 1 and multiply these integers to obtain 405. This is the first factorization. Next choose the second rightmost and the second leftmost entry to obtain the 2nd factorization which also produces 405.
The prime factorization or integer factorization of 405 means determining the set of prime numbers which, when multiplied together, produce the original number 405. This is also known as prime decomposition of 405.
