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 Solution by Chris, PhD)

1034429177995381247 = 51551×20066132140897. Both have 19 digits.

So does 1034429177995381249 = 17×60848775176198897.

I haven't checked the others.
