The factors of 121 and the prime factors of 121 differ because hundred and twenty-one is a composite number. Also, despite being closely related, the prime factors of 121 and the prime factorization of 121 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 121? and everything else you want to know about the topic.
What are the Factors of 121?
They are: 121, 11, 1. These are all the factors of 121, and every entry in the list can divide 121 without rest (modulo 0). That’s why the terms factors and divisors of 121 can be used interchangeably.
As is the case for any natural number greater than zero, the number itself, here 121, as well as 1 are factors and divisors of 121.
Prime Factors of 121
The prime factors of 121 are the prime numbers which divide 121 exactly, without remainder as defined by the Euclidean division. In other words, a prime factor of 121 divides the number 121 without any rest, modulo 0.
For 121, the prime factors are: 11. By definition, 1 is not a prime number.
Besides 1, what sets the factors and the prime factors of the number 121 apart is the word “prime”. The former list contains both, composite and prime numbers, whereas the latter includes only prime numbers.
Prime Factorization of 121
The prime factorization of 121 is 11 x 11. This is a unique list of the prime factors, along with their multiplicities. Note that the prime factorization of 121 does not include the number 1, yet it does include every instance of a certain prime factor.
121 is a composite number. In contrast to prime numbers which only have one factorization, composite numbers like 121 have at least two factorizations.
To illustrate what that means select the rightmost and leftmost integer in 121, 11, 1 and multiply these integers to obtain 121. This is the first factorization. Next choose the second rightmost and the second leftmost entry to obtain the 2nd factorization which also produces 121.
The prime factorization or integer factorization of 121 means determining the set of prime numbers which, when multiplied together, produce the original number 121. This is also known as prime decomposition of 121.
