Equimultiple
EQUIMUL'TIPLE, adjective [Latin oequus and multiplico or multiplex.]
Multiplied by the same number or quantity.
EQUIMUL'TIPLE, noun In arithmetic and geometry, a number multiplied by the same number or quantity. Hence equimultiples are always in the same ratio to each other, as the simple numbers or quantities before multiplication. If 6 and 9 are multiplied by 4, the multiples, 24 and 36, will be to each other as 6 to 9.
