Question

What place value is higher then one hundred Gigillion?

Answer

Names for large numbers have been used with various different definitions resulting in a lot of confusion. The term "gigillion" is mostly used informally to mean very, very many in much the same way that people say there were millions of people, toys, books, etc. where it is not meant literally at all, and the numbers of items involved may be around a hundred or a thousand for example. But "gigillion" is also sometimes defined as a precise number. To start with, the "American" and "British" systems of naming numbers larger than a million differ, where in the American system "one billion" means 1000 million, and in the British system "one billion" means a million million. The term "gillion" has been proposed as part of a Greek-based system that differs from both the American and British systems, and some number names in all 3 systems are summarized in the table below: Number American name British name Proposed Greek-based name 1,000 = 10^3 Thousand Thousand Thousand 1,000,000 = 10^6 Million Million Million 1,000,000,000 = 10^9 Billion Thousand million Gillion 1,000,000,000,000 = 10^12 Trillion Billion Tetrillion 10^15 Quadrillion Thousand billion Pentillion 10^18 Quintillion Trillion Hexillion 10^21 Sextillion Thousand trillion Heptillion 10^24 Septillion Quadrillion Oktillion 10^27 Octilllion Thousand quadrillion Ennillion 10^30 Nonillion Quintillion Dekillion 10^33 Decillion Thousand quintillion Hendekillion Reference: http://www.unc.edu/~rowlett/units/large.html Now, to a "gigillion": There is a proposed extension of the American system to larger numbers that includes the following definitions: Tetracontillion = 10^(3x10^120+3) Pentacontillion = 10^(3x10^150+3) Hexacontillion = 10^(3x10^180+3) Heptacontillion = 10^(3x10^210+3) Octacontillion = 10^(3x10^240+3) Ennacontillion = 10^(3x10^270+3) Hectillion = 10^(3x10^300+3) Killillion = 10^(3x10^3000+3) Megillion = 10^(3x10^3million+3) Gigillion = 10^(3x10^3billion+3) Terillion = 10^(3x10^3trillion+3) Petillion = 10^(3x10^3quadrillion+3) Exillion = 10^(3x10^3quintillion+3) Zettillion = 10^(3x10^3sextillion+3) Yottillion = 10^(3x10^3septillion+3) Xennillion = 10^(3x10^3octillion+3) Vekillion = 10^(3x10^3nonillion+3) Mekillion = 10^(3x10^3decillion+3) Duekillion = 10^(3x10^3undecillion+3) Trekillion = 10^(3x10^3doedecillion+3) Tetrekillion = 10^(3x10^3tridecillion+3) Reference: http://thomas.muetsch.bei.t-online.de/zahlen.html If this is what you mean by a gigillion, then numbers with additional place values such as 10 gigillion, 100 gigillion, and 1000 gigillion make sense. I hope this information is helpful. If you still have any questions about these numbers, please ask!
