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.
The factors of a number cannot be greater than the number itself. So there are no factors of 4 between 30 and 50.
Any prime number
64.
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.

composite number! ;)
A prime number.
Yes.
That's a prime number.
In number theory, an abundant number is a number for which the sum of its proper divisors is greater than the number itself.
' 1 ' and itself.
16 is a number that has four identical even factors.
No because a abundant # is a number where the sum of its proper factors is greater than itself. 16 is not an abundant number because the sum of its proper factors is (15) less than itself.
A prime number is a number, greater than 1, that has only two factors: 1, and the number itself.
