<mathematics> " Abundant number, 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 deficient number, as 14, whose aliquot parts are 1, 2, 7, the sum of which is 10; and to a perfect number, which is equal to the sum of its aliquot parts, as 6, whose aliquot parts are 1, 2.
Origin: OE. (h)abundant, aboundant, F. Abondant, fr. L. Abudans, p. Pr. Of abundare. See Abound.
