FORMULA
a(n) = floor(1/(1-fract(e^A153704(n)))), where fract(x) = x-floor(x).
EXAMPLE
a(2) = 23, since 1-(1/24) = 0.9583... > fract(e^A153704(2)) = fract(e^8) = 0.95798... >= 0.95652... >= 1-(1/23).
MATHEMATICA
A153704 = {1, 8, 19, 178, 209, 1907, 32653, 119136, 220010};
Table[fp = FractionalPart[E^A153704[[n]]]; m = Floor[1/fp];
