There is no biggest, last number … except infinity. Except infinity isn't a number. But some infinities are literally bigger than others.
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.
Beyond the infinity known as ℵ0 (the cardinality of the natural numbers) there is ℵ1 (which is larger) … ℵ2 (which is larger still) … and, in fact, an infinite variety of different infinities.
A googolplex is 10 raised to the power of a googol, that is it's one followed by a googol of zeroes." A googolplex is so large, there is not enough matter in existence to write it longhand. As numbers increase towards infinity, mathematicians know less and less about them.
Zillion, gazillion, or prillion are quite large numbers. They can be even large if we use terms like mega in front of them, such as “Mega-Million.” People use these terms because they don't know the proper names for bigger terms or what comes after trillion.
The next number after trillion is quadrillion, or a 1 with 15 zeros after it: 1,000,000,000,000,000.
a cardinal number represented in the U.S. by 1 followed by 303 zeros, and in Great Britain by 1 followed by 600 zeros.
Written out in ordinary decimal notation, it is 1 followed by 10100 zeroes; that is, a 1 followed by a googol of zeroes.
What comes after million, billion, and trillion? quadrillion, quintillion, sextillion, septillion, octillion, nonillion, and decillion.
God is neither finite nor infinite and his greatness is beyond infinity. Augustine is original in combining these three aspects in his philosophy, and all three aspects can again be found in Cantor.
With this definition, there is nothing (meaning: no real numbers) larger than infinity.
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.
Googolplex may well designate the largest number named with a single word, but of course that doesn't make it the biggest number. In a last-ditch effort to hold onto the hope that there is indeed such a thing as the largest number… Child: Infinity! Nothing is larger than infinity!
A googolplex is a 1 followed by a googol of zeros.
It's impossible to write out, but in scientific notation it looks like 1 x 1010^100.
Googol is 10 to the 100th power, which is 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. Googolplex isn't just that number but has that many zeros in it.
Zillion has an indeterminate number of zeroes.
Despite the popular misconception, a zillion actually is not a true number.
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...
Quattuorvigintillion. A unit of quantity equal to 1075 (1 followed by 75 zeros).
A unit of quantity equal to 1066 (1 followed by 66 zeros).
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.
The next big number after a trillion is a quadrillion, which is 1,000 trillion.
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.
