Find the longest(?) string of consecutive frugal numbers.

Def: A frugal number is a natural number that has more digits than the number of digits in its prime factorization (including exponents). For example, 128=2^7 and 29282=2*11^4

(In reply to re(2): interesting side topic -- economical numbers -- transcription error compounded by Charlie)

10990400 = 2^6 * 5^2 * 6869; again I haven't checked the others, but just spotted the (obvious) typo.
