Two naming scales for large numbers have been used in English and other European languages since the early modern era: the long and short scales.
Definition of vigintillion
a cardinal number represented in the U.S. by 1 followed by 63 zeros, and in Great Britain by 1 followed by 120 zeros. amounting to one vigintillion in number.
US : a number equal to 1 followed by 63 zeros see Table of Numbers. also, British : a number equal to 1 followed by 120 zeros see Table of Numbers.
Numeral. (dated, British & Australian, long scale) A million quadrillion: 1 followed by 30 zeros, 1030.
A unit of quantity equal to 1099 (1 followed by 99 zeros).
But fair warning, Googolplex Written Out spans this many volumes: 10,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000. Each of those volumes holds a million zeros.
Written out in ordinary decimal notation, it is 1 followed by 10100 zeroes; that is, a 1 followed by a googol of zeroes.
Now, after a trillion, there comes a number known as quadrillion, and then we have other numbers following it. These numbers are quintillion, sextillion, septillion, octillion, nonillion, and decillion.
A "googol" is the number 1 followed by 100 zeroes. The biggest number with a name is a "googolplex," which is the number 1 followed by a googol zeroes.
The number 1,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000. One thousand novemdecillion is a vigintillion.
noun, plural sex·de·cil·lions, (as after a numeral) sex·de·cil·lion. a cardinal number represented in the U.S. by 1 followed by 51 zeros, and in Great Britain by 1 followed by 96 zeros.
Trevigintillion. A unit of quantity equal to 1072 (1 followed by 72 zeros).
The next number after trillion is quadrillion, or a 1 with 15 zeros after it: 1,000,000,000,000,000.
What's bigger than a googolplex? Even though a googolplex is immense, Graham's number and Skewes' number are much larger. Named after mathematicians Ronald Graham and Stanley Skewes, both numbers are so large that they can't be represented in the observable universe.
Google is the word that is more common to us now, and so it is sometimes mistakenly used as a noun to refer to the number 10100. That number is a googol, so named by Milton Sirotta, the nephew of the American mathematician Edward Kasner, who was working with large numbers like 10100.
Everyone loves to pull out infinity, or the fabled “infinity plus one.” Maybe if you were inclined to do so, you pulled out the googol or the googolplex. Smaller than infinity, but really big numbers each. But as you probably figured, infinity doesn't really count.
Zillion sounds like an actual number because of its similarity to billion, million, and trillion, and it is modeled on these real numerical values. However, like its cousin jillion, zillion is an informal way to talk about a number that's enormous but indefinite.
With this definition, there is nothing (meaning: no real numbers) larger than infinity.
A googol, officially known as ten-duotrigintillion or ten thousand sexdecillion, is a 1 with one hundred zeros after it. Written out, a googol looks like this: 10,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000.
A unit of quantity equal to 10120 (1 followed by 120 zeros).
The concept of infinity varies accordingly. Mathematically, if we see infinity is the unimaginable end of the number line. As no number is imagined beyond it(no real number is larger than infinity). The symbol (∞) sets the limit or unboundedness in calculus.
