Line 16:
The first number whose proper divisor product won't fit in signed 64 bits is 240, with pdp 2641807540224000000000 (22 digits).<br>

:The precision limits are 180 for 64-bit IEEE-754 floats and (again) 240 for 80-bit floats. --[[User:Petelomax|Petelomax]] ([[User talk:Petelomax|talk]]) 01:50, 2 October 2022 (UTC)
