No, 1 is not considered a Prime number. By definition, a prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. Since 1 only has one positive divisor (itself), it does not meet the criteria to be classified as a prime number.

Vivi1 was considered a prime number for many years. But there is a problem: any number can be written as the product of its prime factors. E.g. 30 = 2*3*5 (2,3 and 5 being primes). If 1 is a prime, then the prime factorization of 30 could be 2*3*5*1 or even 2*3*5*1*1*1*1.
So mathematicians had to say "primes, but not 1!" all the time.
Therefore 1 is no longer (mostly for practical reasons) considered prime.

How many prime numbers between 1 and 8888888888888888888888888888888888888888888888?
To determine the number of prime numbers between 1 and 8888888888888888888888888888888888888888888888, we can use the Prime Number Theorem. This theorem states that the density of prime numbers around a large number n is approximately 1/ln(n). Therefore, the number of prime numbers between 1 and 8888888888888888888888888888888888888888888888 can be estimated by dividing ln(8888888888888888888888888888888888888888888888) by ln(2), which gives approximately 1.33 x 10^27 prime numbers.
Is 1 a mersenne prime?
1 is not a Mersenne prime because 21 - 1 = 2 - 1 = 1 and 1 is not a prime number.
Is 1 a prime or prime?
No 1 is neither a prime number or a composite number
Is 1 a prime number or not?
1 is not a prime number. By definition, a prime number has exactly two distinct divisors: 1 and itself. Thus, 1 cannot be a prime.
