Trying 701880
it is my first aliquot sequences calculations, but my computer works slowly ! PS for my first trial I have advanced 780906 i:646 to i:648, and advanced one step with 701760 and 2576960768...

Done with 704700, 114 Digits, c113, 2^4  no driver and the 2^4 could easily change if it has only 2 factors (minimum is 2^3) High cofactor though (not fully ecm'ed)
Done with 704376, 112 Digits, c111, 2^3*3  A fairly persistent guide.
