Factors of 15

The factors of 15 and the prime factors of 15 differ because fifteen is a composite number. Also, despite being closely related, the prime factors of 15 and the prime factorization of 15 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 15? and everything else you want to know about the topic.

What are the Factors of 15?

They are: 15, 5, 3, 1. These are all the factors of 15, and every entry in the list can divide 15 without rest (modulo 0). That’s why the terms factors and divisors of 15 can be used interchangeably.

As is the case for any natural number greater than zero, the number itself, here 15, as well as 1 are factors and divisors of 15.

Prime Factors of 15

The prime factors of 15 are the prime numbers which divide 15 exactly, without remainder as defined by the Euclidean division. In other words, a prime factor of 15 divides the number 15 without any rest, modulo 0.

For 15, 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 15 apart is the word “prime”. The former list contains both, composite and prime numbers, whereas the latter includes only prime numbers.

Prime Factorization of 15

The prime factorization of 15 is 3 x 5. This is a unique list of the prime factors, along with their multiplicities. Note that the prime factorization of 15 does not include the number 1, yet it does include every instance of a certain prime factor.

15 is a composite number. In contrast to prime numbers which only have one factorization, composite numbers like 15 have at least two factorizations.

To illustrate what that means select the rightmost and leftmost integer in 15, 5, 3, 1 and multiply these integers to obtain 15. This is the first factorization. Next choose the second rightmost and the second leftmost entry to obtain the 2nd factorization which also produces 15.

The prime factorization or integer factorization of 15 means determining the set of prime numbers which, when multiplied together, produce the original number 15. This is also known as prime decomposition of 15.
