After a billion, of course, is **trillion**. Then comes quadrillion, quintrillion, sextillion, septillion, octillion, nonillion, and decillion.

In the American system each of the denominations above 1,000 millions (the American billion) is 1,000 times the preceding one (one trillion = 1,000 billions; one quadrillion = 1,000 trillions).

It takes about 32,000 years to finish 1 trillion seconds. [Note: The values which are greater than a trillion are called Quadrillion (1015)and Quintillion (1018).]

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.

We can define a quadrillion as 1 with 15 zeros after it. It can written as 1,000,000,000,000,000. You can remember it as 5 groups of 3 zeros after the 1.

Of course trillion is not the biggest number. There's quadrillion, quintillion, sextillion, septillion, octillion, nonillion, decillion and more. Each is a thousand of the previous one. There's even a humongous number called vigintillion, a one with 63 zeros.

No, gazillion is not a specific number. It is an informal term that refers to a large quantity of something. Examples: 'Mary has a gazillion stamps in her collection.

Googol. It is a large number, unimaginably large. It is easy to write in exponential format: 10^{100}, 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”.

Today, there are no known trillionaires in the world. But there are more billionaires than ever before and a handful of companies with a trillion-dollar market cap.

"There is no numbers after infinite." Hi Arun, Infinity is not a number. It is a concept of an object that is larger than any real number that does not have a finite end in the sequence.

A googol is 10 to the 100th power, which is 1 followed by 100 zeros. While this is an unimaginably large number, there's still an infinite quantity of larger numbers. One such number is googolplex, which is 10 to the power of a googol, or 1 followed by a googol of zeros.

As an interesting side-note, most European countries use a slightly different naming convention for large numbers and refer to our trillion, as a “thousand billion” they reserve the word trillion for a million billion or 1,000,000,000,000,000,000.

/ˈtrɪljɪn/ A trillion is 1,000,000,000,000, also known as 10 to the 12th power, or one million million.

It's a thousand billion. It's a one followed by 12 zeros.

The number 42 is, in The Hitchhiker's Guide to the Galaxy by Douglas Adams, the "Answer to the Ultimate Question of Life, the Universe, and Everything," calculated by an enormous supercomputer named Deep Thought over a period of 7.5 million years.

There is no number before infinity. It is possible to represent infinity minus one as a mathematical expression, but it does not actually equal anything or have any real mathematical value.

The biggest number can never be called as there is no biggest number.

noun, plural cen·til·lions, (as after a numeral) cen·til·lion. a cardinal number represented in the U.S. by 1 followed by 303 zeros, and in Great Britain by 1 followed by 600 zeros.

sextillion. noun. sex·til·lion sek-ˈstil-yən. US : a number equal to 1 followed by 21 zeros see number. also, British : a number equal to 1 followed by 36 zeros see number.

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.

After a billion, of course, is trillion. Then comes quadrillion, quintrillion, sextillion, septillion, octillion, nonillion, and decillion.

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 10^{10}^{^}^{100}.
