The factors of 490 and the prime factors of 490 differ because four hundred and ninety is a composite number. Also, despite being closely related, the prime factors of 490 and the prime factorization of 490 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 490? and everything else you want to know about the topic.
What are the Factors of 490?
They are: 490, 245, 98, 70, 49, 35, 14, 10, 7, 5, 2, 1. These are all the factors of 490, and every entry in the list can divide 490 without rest (modulo 0). That’s why the terms factors and divisors of 490 can be used interchangeably.
As is the case for any natural number greater than zero, the number itself, here 490, as well as 1 are factors and divisors of 490.
Prime Factors of 490
The prime factors of 490 are the prime numbers which divide 490 exactly, without remainder as defined by the Euclidean division. In other words, a prime factor of 490 divides the number 490 without any rest, modulo 0.
For 490, the prime factors are: 2, 5, 7. By definition, 1 is not a prime number.
Besides 1, what sets the factors and the prime factors of the number 490 apart is the word “prime”. The former list contains both, composite and prime numbers, whereas the latter includes only prime numbers.
Prime Factorization of 490
The prime factorization of 490 is 2 x 5 x 7 x 7. This is a unique list of the prime factors, along with their multiplicities. Note that the prime factorization of 490 does not include the number 1, yet it does include every instance of a certain prime factor.
490 is a composite number. In contrast to prime numbers which only have one factorization, composite numbers like 490 have at least two factorizations.
To illustrate what that means select the rightmost and leftmost integer in 490, 245, 98, 70, 49, 35, 14, 10, 7, 5, 2, 1 and multiply these integers to obtain 490. This is the first factorization. Next choose the second rightmost and the second leftmost entry to obtain the 2nd factorization which also produces 490.
The prime factorization or integer factorization of 490 means determining the set of prime numbers which, when multiplied together, produce the original number 490. This is also known as prime decomposition of 490.
