The factors of 728 and the prime factors of 728 differ because seven hundred and twenty-eight is a composite number. Also, despite being closely related, the prime factors of 728 and the prime factorization of 728 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 728?* and everything else you want to know about the topic.

## What are the Factors of 728?

They are: 728, 364, 182, 104, 91, 56, 52, 28, 26, 14, 13, 8, 7, 4, 2, 1. These are all the factors of 728, and every entry in the list can divide 728 without rest (modulo 0). That’s why the terms factors and divisors of 728 can be used interchangeably.

As is the case for any natural number greater than zero, the number itself, here 728, as well as 1 are factors and divisors of 728.

## Prime Factors of 728

The prime factors of 728 are the *prime* numbers which divide 728 exactly, without remainder as defined by the Euclidean division. In other words, a prime factor of 728 divides the number 728 without any rest, modulo 0.

For 728, **the prime factors are: 2, 7, 13**. By definition, 1 is not a prime number.

Besides 1, what sets the factors and the prime factors of the number 728 apart is the word “prime”. The former list contains both, composite and prime numbers, whereas the latter includes only prime numbers.

## Prime Factorization of 728

The prime factorization of 728 is 2 x 2 x 2 x 7 x 13. This is a unique list of the prime factors, along with their multiplicities. Note that the prime factorization of 728 does not include the number 1, yet it does include every instance of a certain prime factor.

728 is a composite number. In contrast to prime numbers which only have one factorization, composite numbers like 728 have at least two factorizations.

To illustrate what that means select the rightmost and leftmost integer in 728, 364, 182, 104, 91, 56, 52, 28, 26, 14, 13, 8, 7, 4, 2, 1 and multiply these integers to obtain 728. This is the first factorization. Next choose the second rightmost and the second leftmost entry to obtain the 2nd factorization which also produces 728.

The prime factorization or integer factorization of 728 means determining the set of prime numbers which, when multiplied together, produce the original number 728. This is also known as prime decomposition of 728.
