Can a square number be a prime number why or why not?
No, square numbers (other than 1) have more than two factors.
What are two examples of a type of number that has an odd number factor?
There are square numbers (numbers which are a square of an integer), such as 4. It's factors, listed are 1, 2, and 4. All square numbers have an odd number of factors. Then there's 1, which has only 1 factor: 1. All other numbers have an even number of factors. Prime numbers will have only 2 factors (2 is even).
Is 7 a square?
No 7 is not a square number but it is a prime number because it has only two factors which are itself and one.
Reasons why square numbers are said to be composite numbers?
Prove the opposite.Assume that a square number is prime.A square number is one that is a product of a number multiplied by itselfA prime number is one that has no factors other than itself and 1.For a prime number to be square, the only choice is for it to be 1*1=1Since 1 is not a prime number, there is a contradiction, and the original premise is false.Therefore, all square numbers must be composite.â–
Why arnt there any square prime numbers?
Prime numbers only have two factors; square numbers (other than 1) have more than two.
How is the number of factors of square numbers different from the number of factors for other numbers?
Square numbers have an odd number of factors.
What is a square factor?
They are square factors that are factors of other numbers as for example 9 is a square number that is a factor of 27

How many factors do perfect square numbers have?
It depends what square number you're looking at. The square number 25 has only three factors (1, 5 and 25) but the square number 16 has 5 (1, 2, 4, 8 and 16.) A key point is that the factors don't pair up. There is always one middle factor that is the square root of the number and so cannot pair with any other factor. This means that all square numbers have an odd number of factors, while other numbers have an even number of factors.
Explain why a prime number can't be a square number?
Prime numbers have two factors. All square numbers (other than 1) have more than that.

Are any prime numbers also square numbers?
No. That is impossible. A prime number is defined as a number that factors only to itself and the number one. A prime number MUST only be "divisible" by 1 and itself to get an integer number. For example, 7 only has 2 factors - 1 and 7. Square numbers are divisible by a number other than 1 and itself. For example, 16 has the factors 1, 2, 4, 8, and 16. 4 squared = 16
What numbers you can multiply to get a number are called factors or addends?
Factors are numbers that can be multiplied together to get other numbers. Factors are important in algebra and algebra II.

What is the largest 3 digit prime number whose square root is a prime number?
There is no three digit prime number whose square root is a prime number. Prime numbers have no factors other than 1 and themselves. Any number having a prime number as a square root is a composite number.
