What comes after 1 trillion?

After 1 trillion (1,000,000,000,000), the next named number in the short scale system is one quadrillion, which is 1 followed by 15 zeros (1,000,000,000,000,000). This follows the pattern where each new major number name (million, billion, trillion, quadrillion, etc.) adds three more zeros (or a factor of a thousand).

Is 1 zillion a real number?

Zillion is not actually a real number; it's simply a term used to refer to an undetermined but extremely large quantity.

Are billion and milliard the same?

Yes, "milliard" and "billion" refer to the same quantity (1,000,000,000 or a thousand million), but usage differs: "billion" (short scale) is standard in the US and now the UK (since 1974), while "milliard" (long scale term) is used in many European languages and older British English, causing historical confusion.
 

What is the largest named number?

The largest finite number with a widely recognized name is the googolplex (10googol10 raised to the googol power10googol or 101010010 raised to the exponent 10 to the 100th power end-exponent1010100), but Graham's number (g64) is vastly larger, used in a serious mathematical proof, and is considered the largest number used in such a proof. Beyond these, there are theoretical numbers like Rayo's number, defined as the smallest number larger than any number named by an expression using a googol symbols or less in a specific language, showing names can be defined for arbitrarily huge numbers.
 

Why is 52 an untouchable number?

The number 52 is an "untouchable number" because it's a rare number that can't be formed by adding up the proper divisors (all divisors except the number itself) of any other integer, making it a member of a special set of numbers that are "untouched" by this specific mathematical operation, joining other untouchables like 2 and 5 in this category.

Is 1 octillion a real number?

Yes, octillion is a number, specifically a very large one, representing 1 followed by 27 zeros (102710 to the 27th power1027) in the short scale used in the U.S. and modern English, or 1 followed by 48 zeros (104810 to the 48th power1048) in the long scale (British/European). It's a cardinal number derived from the Latin prefix "octo-" (eight) and used in scientific and theoretical contexts for immense quantities, like atoms in a body or stars in the universe, though powers of ten are more common. 

Is vigintillion a real number?

Yes, vigintillion is a real number name, but its value differs between the short scale (US) and long scale (UK/Europe), representing 106310 to the 63rd power1063 (1 followed by 63 zeros) in the short scale and 1012010 to the 120th power10120 (1 followed by 120 zeros) in the long scale, making it a valid, though rarely used, term for a massive quantity. 

How many zeros are in 1 sextillion?

A sextillion has 21 zeros in the short scale system (used in the U.S. and modern English), written as 1,000,000,000,000,000,000,000 (1 followed by 21 zeros), or 102110 to the 21st power1021. In the long scale (older British system), it's much larger (1 followed by 36 zeros). 

Is 170141183460469231731687303715884105727 prime number?

Using this algorithm with hand computations on paper, Lucas showed in 1876 that the 39-digit number (2127 – 1) equals 170,141,183,460,469,231,731,687,303,715,884,105,727, and that value is prime. Also known as M127, this number remains the largest prime verified by hand computations.

Why do Americans not use milliards?

Probably because of the way people write numbers in groups of 3. The use of " milliard " for 109 seems to be a dutch or german innovation. American English started using the short scale from the French influence in the 18th century, around the time the two countries were influencing each other to have revolutions.

What is the Roman numeral for billion?

A billion (1,000,000,000) in Roman numerals is represented by an M with two horizontal bars over it, like Mcap M𝑀, or by using parentheses for multiplication: ((M))open paren open paren cap M close paren close paren((𝑀)) or sometimes Mcap M𝑀 with a vinculum (double overline) for a thousand millions. While traditional Roman numerals didn't have a single symbol for a billion, this modern extension uses bars or brackets to multiply by thousands. 

Do any trillionaires exist?

While it sounds like a real number because it uses the "-illion" suffix, it's a whimsical coinage, not a mathematical constant, used to express "a whole lot" or "too many to count".
