Yes it is.
Here are the first few deficient numbers:
1, 2, 3, 4, 5, 7, 8, 9, 10, 11, 13, 14, 15, 16, 17, 19, 21
13 is deficient.
Yes, like all primes, 13 is deficient.
Yes.
The factors of 26 are 1, 2, 13. And if you add them together (1+2+13) the answer is 16 which is less than 26 so it is an deficient number.
Because all of its factors also known as 13 and 1 add up to be more than the number itself 13.
