# Factors of 1000

The factors of 1000 and the prime factors of 1000 differ because thousand is a composite number. Also, despite being closely related, the prime factors of 1000 and the prime factorization of 1000 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 1000? and everything else you want to know about the topic.

## What are the Factors of 1000?

They are: 1000, 500, 250, 200, 125, 100, 50, 40, 25, 20, 10, 8, 5, 4, 2, 1. These are all the factors of 1000, and every entry in the list can divide 1000 without rest (modulo 0). That’s why the terms factors and divisors of 1000 can be used interchangeably.

As is the case for any natural number greater than zero, the number itself, here 1000, as well as 1 are factors and divisors of 1000.

## Prime Factors of 1000

The prime factors of 1000 are the prime numbers which divide 1000 exactly, without remainder as defined by the Euclidean division. In other words, a prime factor of 1000 divides the number 1000 without any rest, modulo 0.

For 1000, the prime factors are: 2, 5. By definition, 1 is not a prime number.

Besides 1, what sets the factors and the prime factors of the number 1000 apart is the word “prime”. The former list contains both, composite and prime numbers, whereas the latter includes only prime numbers.

## Prime Factorization of 1000

The prime factorization of 1000 is 2 x 2 x 2 x 5 x 5 x 5. This is a unique list of the prime factors, along with their multiplicities. Note that the prime factorization of 1000 does not include the number 1, yet it does include every instance of a certain prime factor.

1000 is a composite number. In contrast to prime numbers which only have one factorization, composite numbers like 1000 have at least two factorizations.

To illustrate what that means select the rightmost and leftmost integer in 1000, 500, 250, 200, 125, 100, 50, 40, 25, 20, 10, 8, 5, 4, 2, 1 and multiply these integers to obtain 1000. This is the first factorization. Next choose the second rightmost and the second leftmost entry to obtain the 2nd factorization which also produces 1000.

The prime factorization or integer factorization of 1000 means determining the set of prime numbers which, when multiplied together, produce the original number 1000. This is also known as prime decomposition of 1000.
