25 is a square number that is a factor of 50 and a multiple of the prime number 5.
The only prime factor of 4 is 2. No prime number is a multiple of 5.
If 21 is a multiple of the number, the number cannot have 90 as a factor.
A multiple of 13 will be a composite number. Because the number will have 13 as a factor, it cannot be a prime number.

No multiple of 86 is in that range. 43 is a prime number that is a factor of 86.
Except in this case, the largest square factor is 1.
The answer depends on whether or not the prime number is a factor of the other number.If the prime number is a factor of the other number then the GCF is the prime, otherwise the GCF is 1.
The largest square factor of 557 is 1 because 557 is a prime number
A factor can or cannot be a prime number Ex: 2 is the factor of all other even numbers its a prime number but 9 is a factor of 18 and its not a prime number A prime is a factor but a factor being a prime number varies
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.
Usually it's 1, unless the composite number is a multiple of the prime number. Then, it's the prime number.
