Just 1.
Absolutely not. A square number has an integer square root, so by definition it has at least one factor. Prime numbers have no factors
All numbers have factors. Some factors are prime numbers. A prime factor is a factor that is a prime number. A common prime factor is a prime factor that appears on the list of factors of two or more given numbers.
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.
Because prime numbers only have one factor pair.
Perfect squares are positive. A smallest negative number doesn't exist. The four smallest prime numbers are 2, 3, 5 and 7. The smallest perfect square would have to be 2^2 x 3^2 x 5^2 x 7^2 or 44,100
A [perfect] square number, by definition, has a factor which is its square root. As a result it CANNOT be a prime!
1, 4 and 16 are square numbers that are factors of 32. Of these, 4 and 16 have two as their only prime factor and 1 is odd.
There are: 3 is a prime and it is the square of √3.There are no primes that are perfect squares since, by definition, a perfect square is of the form n2 = n*n. And for n > 1 , n is a factor of n2. If n = 1, then n2 = 1 which is not a prime since it is only divisible by 1.

No, there are no prime numbers that are also square numbers. Prime numbers are only divisible by 1 and themselves, while square numbers have integer square roots. Since the square root of a prime number is not an integer, a prime number cannot be a square number.
25. The prime factorisation of 350 is: 2 x 52 x 7 The prime factorisation of a perfect square has an even power of every prime. From the prime factorisation of 350, the highest possible square is 20 x 52 x 70 = 25.
You look for a perfect square among its factors; if you factor it into prime factors, you would look for a repeated prime factor. Then you take that factor out of the root sign (taking the square root of it, while you do it).
Since 30 does not have any square factors greater than one, the expression is in its simplest form.
44,100
Except in this case, the largest square factor is 1.
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.
25 is a square number that is a factor of 50 and a multiple of the prime number 5.
