What are the Factors of 642?

They are: 642, 321, 214, 107, 6, 3, 2, 1. These are all the factors of 642, and every entry in the list can divide 642 without rest (modulo 0). That’s why the terms factors and divisors of 642 can be used interchangeably.

As is the case for any natural number greater than zero, the number itself, here 642, as well as 1 are factors and divisors of 642.

Prime Factors of 642

The prime factors of 642 are the prime numbers which divide 642 exactly, without remainder as defined by the Euclidean division. In other words, a prime factor of 642 divides the number 642 without any rest, modulo 0.

For 642, the prime factors are: 2, 3, 107. By definition, 1 is not a prime number.

Besides 1, what sets the factors and the prime factors of the number 642 apart is the word “prime”. The former list contains both, composite and prime numbers, whereas the latter includes only prime numbers.

Prime Factorization of 642

The prime factorization of 642 is 2 x 3 x 107. This is a unique list of the prime factors, along with their multiplicities. Note that the prime factorization of 642 does not include the number 1, yet it does include every instance of a certain prime factor.

642 is a composite number. In contrast to prime numbers which only have one factorization, composite numbers like 642 have at least two factorizations.

To illustrate what that means select the rightmost and leftmost integer in 642, 321, 214, 107, 6, 3, 2, 1 and multiply these integers to obtain 642. This is the first factorization. Next choose the second rightmost and the second leftmost entry to obtain the 2nd factorization which also produces 642.

The prime factorization or integer factorization of 642 means determining the set of prime numbers which, when multiplied together, produce the original number 642. This is also known as prime decomposition of 642.
