The factors of 861 and the prime factors of 861 differ because eight hundred and sixty-one is a composite number. Also, despite being closely related, the prime factors of 861 and the prime factorization of 861 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 861? and everything else you want to know about the topic.
What are the Factors of 861?
They are: 861, 287, 123, 41, 21, 7, 3, 1. These are all the factors of 861, and every entry in the list can divide 861 without rest (modulo 0). That’s why the terms factors and divisors of 861 can be used interchangeably.
As is the case for any natural number greater than zero, the number itself, here 861, as well as 1 are factors and divisors of 861.
Prime Factors of 861
The prime factors of 861 are the prime numbers which divide 861 exactly, without remainder as defined by the Euclidean division. In other words, a prime factor of 861 divides the number 861 without any rest, modulo 0.
For 861, the prime factors are: 3, 7, 41. By definition, 1 is not a prime number.
Besides 1, what sets the factors and the prime factors of the number 861 apart is the word “prime”. The former list contains both, composite and prime numbers, whereas the latter includes only prime numbers.
Prime Factorization of 861
The prime factorization of 861 is 3 x 7 x 41. This is a unique list of the prime factors, along with their multiplicities. Note that the prime factorization of 861 does not include the number 1, yet it does include every instance of a certain prime factor.
861 is a composite number. In contrast to prime numbers which only have one factorization, composite numbers like 861 have at least two factorizations.
To illustrate what that means select the rightmost and leftmost integer in 861, 287, 123, 41, 21, 7, 3, 1 and multiply these integers to obtain 861. This is the first factorization. Next choose the second rightmost and the second leftmost entry to obtain the 2nd factorization which also produces 861.
The prime factorization or integer factorization of 861 means determining the set of prime numbers which, when multiplied together, produce the original number 861. This is also known as prime decomposition of 861.
