## What is the order of the illions?

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.

## What’s higher than Centillion?

Nonillion: 1,000,000,000,000,000,000,000,000,000,000. Decillion: 1,000,000,000,000,000,000,000,000,000,000,000. Googol: 1 followed by 100 zeros. Centillion: 1 followed by 303 zeros.

What is after Googolplexianth?

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. Astrophysicists estimate the number of atoms to be a one with 82 zeros.

### What is the 10th illion?

Now vigintillion was the largest -illion….2.4. 4 – Saibian’s old style -illions.

Saibian’s Old Style -illions Saibian’s Corrected -illions Value
quintillion quintillion 10^18
sextillion sextillion 10^21
septillion septillion 10^24
octillion octillion 10^27

### What is the highest someone has ever counted?

one million
According to the Guiness Book of World Records, the highest number ever counted to out loud by a person is one million. It took Jeremy Harper, a computer engineer from Birmingham, Alabama, 89 days to complete the task.

What is the highest number in existence?

You can find plenty of huge numbers on the Web. According to the Guinness Book of World Records , the largest lexicographically accepted number is the centillion, which is 10^303 in the American system and 10^600 in the European system.

#### What is quadrillion vs trillion?

One trillion is equal to 1,000,000,000,000 and one quadrillion is equal to 1,000,000,000,000,000 so therefore 1,000,000,000,000,000 / 100,000,000,000,000 = 10.

#### What is the largest number known to man?

Infinity is never reachable; therefore, the biggest number known to man is also unreachable, because, if infinity goes on forever, there is also a number a infinitessimally smaller than infinity, but not infinity. And seeing as infinity is unreachable, so is the largest number known to man.

Which number is the largest?

Infinity, a concept which can be used as a largest number in some contexts Graham’s number, once claimed as the largest number ever used in a serious mathematical proof Dirac large numbers hypothesis, for cosmology.
