According to many books (such as Mathematics, A human Endeavor by Harold Jacobs)2 the googol is one of the largest numbers ever named. The googolplex is 1 followed by a googol zeros. More recently, Skewer's number is the largest number ever used in a mathematical proof.
The immediate response to the question: what comes after a trillion would be quadrillion since that is the number that comes exactly after a trillion. As discussed in our blog, a quadrillion can be defined as 1 with 15 zeros. It can written as 1,000,000,000,000,000.
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.
A unit of quantity equal to 1066 (1 followed by 66 zeros).
a cardinal number represented in the U.S. by 1 followed by 303 zeros, and in Great Britain by 1 followed by 600 zeros.
None of the words jillion, zillion, squillion, gazillion, kazillion, bajillion, or bazillion (or Brazilian) are real numbers.
A unit of quantity equal to 1069 (1 followed by 69 zeros).
Therefore, the number 200000 in words is Two Hundred Thousand.
Quattuorvigintillion. A unit of quantity equal to 1075 (1 followed by 75 zeros).
Then, you finally reach Millinillion. Repeat with those numbers to reach Billinillion. After that comes a Trillinillion, Quadrillinillion, Quintillinillion, Sextillinillion, Septillinillion, Octillinillion, Nonillinillion, and on...
A millillion (alternately millinillion, milliatillion or milletillion) is equal to 103,003 in the short scale, or 106,000 in the long scale (this number is also called Platillion). It is made by combining "mille" (1,000) with the standard -illion suffix, which is itself derived from "mille".
After a billion, of course, is trillion. Then comes quadrillion, quintrillion, sextillion, septillion, octillion, nonillion, and decillion. One of my favorite challenges is to have my math class continue to count by "illions" as far as they can.
1,000,000,000 (one billion, short scale; one thousand million or one milliard, one yard, long scale) is the natural number following 999,999,999 and preceding 1,000,000,001.
A unit of quantity equal to 1078 (1 followed by 78 zeros).
If you write a 1 followed by nine zeros, you get 1,000,000,000 = one billion! That's a lot of zeros! Astronomers often deal with even larger numbers such as a trillion (12 zeros) and a quadrillion (15 zeros).
A unit of quantity equal to 1099 (1 followed by 99 zeros).
The thing is, infinity is not a number, but a concept or idea. 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.
Googol. It is a large number, unimaginably large. It is easy to write in exponential format: 10100, an extremely compact method, to easily represent the largest numbers (and also the smallest numbers). With the smallest of effort, you can also present it in the full format: a “one” followed by one hundred “zeros”.
The longest number with a name is the Googleplexian. A Googolplexian is a number with 10100 zeroes. Whilst larger numbers can be imagined, the Googolplexian is the largest number that could be found in the dictionary.
