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