Factors of 561


The factors of 561 and the prime factors of 561 differ because five hundred and sixty-one is a composite number. Also, despite being closely related, the prime factors of 561 and the prime factorization of 561 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 561? and everything else you want to know about the topic.

What are the Factors of 561?

They are: 561, 187, 51, 33, 17, 11, 3, 1. These are all the factors of 561, and every entry in the list can divide 561 without rest (modulo 0). That’s why the terms factors and divisors of 561 can be used interchangeably.

As is the case for any natural number greater than zero, the number itself, here 561, as well as 1 are factors and divisors of 561.

Prime Factors of 561

The prime factors of 561 are the prime numbers which divide 561 exactly, without remainder as defined by the Euclidean division. In other words, a prime factor of 561 divides the number 561 without any rest, modulo 0.

For 561, the prime factors are: 3, 11, 17. By definition, 1 is not a prime number.

Besides 1, what sets the factors and the prime factors of the number 561 apart is the word “prime”. The former list contains both, composite and prime numbers, whereas the latter includes only prime numbers.

Prime Factorization of 561

The prime factorization of 561 is 3 x 11 x 17. This is a unique list of the prime factors, along with their multiplicities. Note that the prime factorization of 561 does not include the number 1, yet it does include every instance of a certain prime factor.

561 is a composite number. In contrast to prime numbers which only have one factorization, composite numbers like 561 have at least two factorizations.

To illustrate what that means select the rightmost and leftmost integer in 561, 187, 51, 33, 17, 11, 3, 1 and multiply these integers to obtain 561. This is the first factorization. Next choose the second rightmost and the second leftmost entry to obtain the 2nd factorization which also produces 561.

The prime factorization or integer factorization of 561 means determining the set of prime numbers which, when multiplied together, produce the original number 561. This is also known as prime decomposition of 561.
