Prime Numbers
It is 1 because it only has itself as a factor.
The positive integer with only one factor is 1.
No, a prime number has as its only two factors: one and itself. The number 2 satisfies this, but even numbers greater than three would have factors of one and itself, and also have 2 as a factor (because it's even) so then it's not prime.
That's true.
The only positive integer greater than 10 which is a factor of 27 is 27 itself.
The number 2.
A whole number greater than 1 whose only factors is itself and 1 is called a prime factor. 2, 3, 5, 7, and 11, are just a few of them.
It is true.

The question is garbled but I suspect that the answer is "a prime number".
The only factor of 100 that is greater than ten and odd is 25.
One is the only factor of 1.1 has only one factor which is itself
7 is a prime number and therefore its only prime factor is itself.7 is already prime. Its only prime factor is itself.

43 is already prime; its only prime factor is itself.
