A factor that is a perfect square and not equal to 1 is a number that can be expressed as the product of an integer multiplied by itself, such as 4, 9, 16, 25, etc. These numbers have integer square roots and are considered perfect squares because they result from squaring an integer. Perfect squares greater than 1 have factors other than 1 and themselves, making them unique in their factorization.
I suppose you mean a perfect square. The answer is 25.
17 is a prime number. Its only factors are 1 and 7. Since 1 is a perfect square, it is the answer to the question.

I'm assuming you're wondering if a number is a perfect square? Well, memorization will help as will guess and check. However, if you feel like doing it all by hand, simplifying the square will help you determine if it is a perfect square. Example: let's figure out if the number 225 is a perfect square. Let's take 225 and factor it. When you factor this number, you want to look at factoring numbers which are a perfect square in and of themselves. So 22 is 4, but that doesn't factor, how about 52 ? 25 will indeed factor, so we have 25*9 (look at that, 9 is also a factor). If we split it up like this, we have sqrt(25*9). We can take the square root of these individually and multiply them together. sqrt(25)*sqrt(9) = 5*3 = 15. Therefore 225 is a perfect square of 15.
Because anything times itself equals a perfect square and is considered that taking the square root of a perfect square (non negative numbers) which end result does not involve fractions but whole numbers is a perfect square. 1 x 1 = 1 sq.root(1) = 1 2 x 2 = 4 (Perfect square) sq.root(4) = 2
1 is a perfect square.
10 has no perfect square factors (other than the trivial factor 1).
