1 is neither a Prime number, nor a composite number. A prime number is divisible by exactly two factors, 1 and itself. However, 1 is only divisible by one factor: 1. It is called the identity element or unity.
There is an unusual situation in association with the factors of 1.
The only factor of 1 is 1.
The factor pair, if you absolutely need one (but this is stretching it), is 1 x 1.
There is an issue with the proper factors, since the proper factors are the factors less than the number itself, which in this case means less than 1. So, 1 does not have any proper factors.
There is an issue with the prime factors, since its only factor is 1, but 1 is not a prime number. So, it does not really have any prime factors, and thus does not have any distinct prime factors, which is the list of each different prime factor, either. In addition, without prime factors, you cannot have a prime factorization for 1.
NOTE: There cannot be common factors, a greatest common factor, or a least common multiple because "common" refers to factors or multiples that two or more numbers have in common.
1 doesn't have any prime factors.
1,2,3,5,7,11,13,17,19,23,29,31.... A prime number has exactly two factors. 2 is prime (its factors are 1 and 2) 3 is prime (its factors are 1 and 3) 5 is prime (its factors are 1 and 5) 1 is not prime (its only factor is 1, this is 1 factor, not 2) 4 is not prime (it has 3 factors: 1, 2, and 4) 6 is not prime (it has 4 factors: 1, 2, 3, and 6)
The factors of 1993 are: 1 1993 The prime factors are: 1993 is a prime number.
factors: 1, 1291 (prime)prime factors: 1291 (go figure!)
The factors of 401 are: 1 401 The prime factors are: 401 is a prime number.
The factors of 233357 are: 1 233357 The prime factors are: (233357 is a prime number)
factors: 1, 103 prime factors: 103
Seven is a prime number. A prime number has only itself and 1 as factors. So the factors of seven are 1 and 7. 1 and 7
The factors of -41 are 1, -1, 41, -41 41 is prime.
Its prime factors are 1 & 2.
The prime factors are... 1 & 3 !
factors are 1 and 29..... it is a prime number
