They are prime numbers
It is called a perfect number.
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.
Abundant is a number for which the sum of all its proper factors is greater than the number itself. Deficient is a number for which the sum of all its proper factors is less than the number itself. Perfect is a number for which the sum of all its proper factors is the number itself.
That's a prime number.
it's called a composite number [ a number greater than 1 w/ more than two factors.]
Every number greater than 1 has 1 and the number itself as factors. If it has no other factors besides these two factors, it is a prime number. If it has more factors than 1 and itself, it is a composite number.
Every number greater than 1 has the two factors 1 and the number itself.
All numbers greater than 1 have at least two factors. That is because the number can always divide by 1 and itself. If a number has only 2 factors, it is called a prime number. Otherwise, it is called a composite number.

a number with only 2 factors (1 and itself ) is called a prime number
A whole number greater than 1 whose only factors is itself and 1 is called a prime factor. 2, 3, 5, 7, and 11, are just a few of them.
composite number! ;)
A prime number.
Yes.
