The number 1 is neither prime nor composite.
The factors are 1, 3 and 9, while the prime factor is 3. Some people will say that 1 is also a prime factor, but 1 does not fit the definition of prime.
It important that 1 is not prime because a quote says: "A prime number is a natural number that has exactly two different natural number factors. and so i say 1 is not a prime because a prime number has 2 factor 1 and it self and 1 dose not.
A prime number has two factors, 1 and itself. 1 is not considered a prime number as its factors are 1. Following the rule for primes, you could say that its factors are 1 and 1, but 1 and 1 are obviously the same number.
No. You have to have at least two numbers to say whether they are co prime, as it is only if they have a common factor of 1.
1. That is to say, they have no prime factors in common.
It is because of the way in which primes are defined.
ok well i am in prime and composite in math class and this is how: If the number is a prime then it can only have 2 factors. If it has 3 or more it is a composite number. Say 25 has a lot of factors so it is a composite number. And if 1 has only 1 factor then it is a prime number. And there you have prime and composite.
Because 1 has only one factor which is itself
They are relatively prime.
You could say that a prime number is also a multiple of 1. A good definition of prime number is: "a natural number with exactly two distinct factors". This definition explains why 1 is not a prime number.
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.
No, 1 is not prime.
