The number 4
1 and 4
No. That isn't possible: A prime number, by definition, has no smaller factors. A square number does have a smaller factor - the number that is squared.
To factor a square root you must divide a specific number by another number that is a factor of the specific number. The factor of the specific must also be able to be multiplied by itself to equal the specific number. x multiplied by x equals y. For example: The square root of 144 would be 12 because 12 squared (multiplied by itself) is 144.
A prime number is a number with two and only two factors: 1 (also known as unity) and itself. A composite number is a number with more than two factors; in other words, it has at least one factor besides 1 and itself. A square number is one number multiplied by itself, so that means it will have another factor. Thus, it cannot be a prime number.
A [perfect] square number, by definition, has a factor which is its square root. As a result it CANNOT be a prime!
The other number is -5.
Actually it can, if it's not the square of a prime number. For example, 144 is the square of 12; but you can also factor it as 6 x 24.
There are two solutions to the question:- 2 & 3 2 is the square root of 4 - and a factor of 4 (and 8) 3 is the square root of 9 - and is also a factor of 9

Absolutely not. A square number has an integer square root, so by definition it has at least one factor. Prime numbers have no factors
4 is a square number in its own right and 4*4 = 16 which is also a square number
The perfect square factor of 50 is 25 and the perfect square factor for 90 is 9. The perfect square factors for 50x90 25x9. Of course we also have the other factors of 2 and 2x5.
