Longest Consecutive Factorizations
This page lists the LONGEST known case of consecutive numbers
for which the complete prime factorization is known.
Only results with more than 300 digits are recorded
(all numbers must be greater than 10^300, hence must have at least 301 digits).
I do care about the LONGEST only, not the largest, hence I will not list
results which tie the record length with larger terms.
