{Abundant number} (Math.), 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., 3. [1913 Webster]

Syn: Ample; plentiful; copious; plenteous; exuberant; overflowing; rich; teeming; profuse; bountiful; liberal. See {Ample}. [1913 Webster]
