## What Number Comes After Trillion?

I remember when as a child, I was arguing with my friends who would be the richest when we grow up, the argument ended when we got to Trillion and the first person who mentioned Trillion was going to be the richest cos we so believed that was the highest number that existed. I hope you are also not at this table.

What number is after Trillion? Trillion is a “1 with 12 zeros after it”, it looks like this: 1,000,000,000,000. **The next named number after trillion is quadrillion,** which is a 1 with 15 zeros after it: 1,000,000,000,000,000.

Below is a table of numbers beneath Trillion:

For a better understanding and easier reading, the numbers are written with Scientific notations.

Ten-duotrigintillion (or Googol) | 1 x 10^{100} |

Skewer’s Number | 1 x 10^{130} |

Centillion | 1 x 10^{303} |

Googolplex | 1 x 10^{10100} |

Skewes’ Number |

As you can see, throughout the majority of the chart, the power of ten rises by three with each new number, which implies that you must add three more zeros to the end of the previous number to get the next. For instance, a billion is a one followed by nine zeros, or 1,000,000,000. Trillion is a 1 followed by twelve zeros, or 1,000,000,000,000.

This pattern continues until you reach Ten-duotrigintillion, or Googol (yes, this is where search engine Google got their name from). The numbers between Googol, Skewer’s Number, Centillion, and Googolplex have no names.

You may have noticed that the word “zillion” is missing from this list. Zillion is not a real number; it is a colloquial word for an undefined but very big amount.

## Understanding Large Numbers

While the graphic above illustrates all of the significant enormous numbers, what do those numbers really represent and how can they be understood? Although it may be difficult, if not impossible, to comprehend very big numbers, there are a few methods for obtaining a sense of their magnitude. Although trillion is one of the lowest figures on the list, it is still an enormous amount. To count to a trillion would take about 31,709 years!

When written out, a googol, or a one followed by a hundred zeros, appears as follows: 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. When compared to scientific notation, writing a huge number out this way may sometimes convey a more accurate impression of its magnitude.

And how about a googolplex, another of the chart’s gigantic numbers? A googolplex is composed of a single digit followed by a googol zero. A googolplex is such a huge number that it has no known use in mathematics, and some mathematicians and astronomers speculate that it is even larger than the number of atoms in the universe.

However, there are bigger numbers than a googolplex. Skewes’ number was created by mathematician Stanley Skewes and is ten to the tenth to the tenth to the thirty-fourth. Skewes was especially interested in prime numbers, and when his number was presented in 1933, it was dubbed the “biggest number that has ever served any clear function in mathematics” by a colleague.

Skewes’ number, however, has subsequently been surpassed by Graham’s, which is now recognized as the world’s biggest number. R.L. Graham invented Graham’s number, which cannot be expressed in standard notation. It is so vast that even if all everything in the universe were turned to pens and ink, it would still be insufficient to write it out completely.

## Summary: What Comes After Trillion?

What comes next after trillion? Following trillion is quadrillion, or a 1 followed by 15 zeros: 1,000,000,000,000,000. Knowing the names of large numbers is advantageous when dealing with extremely large values or performing higher-level mathematics.

The biggest number known at the moment is Graham’s number, which is much too huge and complex to be written down or imagined.
