What is a number that has four identical even factors greater than 1 and that has only 1 and itself as factors?
A number that has only one and itself as factors is a prime number and so therefore it can't have four other identical factors.
Why are no prime number a perfect number?
The only factors of a prime are 1 and itself. So, the only factor smaller than the number itself is 1. Therefore the sum of all factors smaller than the number is 1. But 1 is not a prime number. Thus, there is no prime number that is a perfect number.
What is the whole number greater then 1 whose only factors are 1 and itself?
That's a prime number.
What is a number greater than one that has two factors called?
If the number 1 is considered a factor, then these are the prime numbers. Their only factors are 1 and themselves.
What whole number is greater than 1 with only two factors 1 and itself?
Any prime number
Luke is looking for a number greater than 12 and less than 40 that has exactly 3 factors what might his number be?
the answer is 25 because you're asking for a number greater than 12 and smaller than 40 and has exactly 3 factors so in that case 25 is the only one.

Composite numbers vs prime numbers?
A composite number is a natural number that can be divided into smaller factors (which are also natural numbers). For example, 6 = 2 x 3. A prime number is an integer (greater than 1) that cannot be separated into smaller factors. For example, 7 can't be divided into smaller factors.

What number is greater than 12 and less than 40 that only has 3 factors?
the answer is 25, the factors are 1,5,25
Will a greater number always have more factors than a smaller number?
No. For example, 30 has the factors 1, 2, 3, 5, 6, 10, 15, 30; while 31 only has the factors 1 and 31 - in other words, it's a prime number. Note that there are arbitrarily large prime numbers (there is no last prime number); each of them has exactly two factors.
What is a whole number greater than 1 with only 2 factors 1 and itself?
A prime number.
Is a prime number a whole number greater than 1 that has only itself and 1 as its factors?
Yes.
What is the whole number greater then 1 whose only factors are 1 and itself?
That's a prime number.

How can a prime number be identified?
A prime number is a number, greater than 1, that has only two factors: 1, and the number itself.
What is a whole number greater than one with only two factors itself and one?
That's a prime number.
