∙ 8y ago1 because 1 can only be divided by itself. 1x1=1 see?
The number ' 1 ' has only one factor.
By definition, all prime numbers have exactly two factors. There is not a prime number that has only one factor.
The number 1 is not a prime number. A prime number has exactly two factors, 1 and the number itself. 1 is the only number having exactly one factor.
No single integer satisfies both requests. 80 is the only integer with exactly 5 factor pairs in that range, but it has two prime factors. 64 and 81 have one prime factor but 4 and 3 factor pairs respectively.

1 is the only number that has exactly one factor. A prime number has exactly two factors, 1 and the number itself. A composite number has more than two factors.
A factor of a integer is an integer that divides the second integer into a third integer exactly; i.e. A is a factor of B if B/A is exactly C, where all of A, B and C are integers. A prime factor is a factor as above, but is also a prime number. This means that the only factors of that factor are one and the number itself; i.e. A is a prime factor of B if B/A is exactly C andthe only factors of A are 1 and A.
I think you already did. Prime numbers have exactly two factors. 1 is not a prime number because it has only one factor.
A prime number (or a prime) is a natural number that has exactly two distinct natural number divisors: 1 and itself.

Any prime number except 1, which only has one factor (since 1 and the number itself are the same).
A prime is a number with exactly two factors, itself and one. Note that 1 is neither prime nor composite, as it has exactly one factor, and that there is only one even prime, 2.
