- n. A number that is less than the sum of all of its divisors except itself.
from the GNU version of the Collaborative International Dictionary of English
- adj. a number, the sum of whose aliquot parts exceeds the number itself. Thus, 1, 2, 3, 4, 6, the aliquot parts of 12, make the number 16. This is opposed to a
deficientnumber, as 14, whose aliquot parts are 1, 2, 7, the sum of which is 10; and to a perfectnumber, which is equal to the sum of its aliquot parts, as 6, whose aliquot parts are 1, 2., 3.
