The name for 10¹⁵ (1 followed by 15 zeros) is a quadrillion, which represents one thousand trillion, used in the short scale system common in English-speaking countries.
Quattuorvigintillion. A unit of quantity equal to 1075 (1 followed by 75 zeros).
A unit of quantity equal to 10300 (1 followed by 300 zeros).
Duoquadragintillion represents a number equal to 10 raised to the power of 129. It is one of the largest known units of quantity used in mathematics. The number contains 1 followed by 129 zeros, signifying its enormous scale.
In addition to those listed in the everyday-use table, the SI includes standardised prefixes for 1015 (peta), 1018 (exa), 1021 (zetta), 1024 (yotta), 1027 (ronna), and 1030 (quetta); and for 10−15 (femto), 10−18 (atto), 10−21 (zepto), 10−24 (yocto), 10−27 (ronto), and 10−30 (quecto).
In the American and British numbering systems, a sextillion is defined as 10 to the power of 21—meaning it's represented by a one followed by 21 zeros. To visualize this number: 1,000,000,000,000,000,000,000 (that's quite an impressive figure!).
vigintillion. a cardinal number represented in the U.S. by 1 followed by 63 zeros, and in Great Britain by 1 followed by 120 zeros.
This sequence does not extend above 52 because it is, an untouchable number, since it is never the sum of proper divisors of any number. It is the first untouchable number larger than 2 and 5.
(hyperbole is common now) Sometimes we make new words that are half joking, for example "Kajillion." This is not a real number, it just represents the idea of an absurdly large amount.
femto- (f-) 10-15. 1 quadrillionth.
The unit prefix mega is a multiplier of 1000000 (106) in the International System of Units (SI). Therefore, one megabyte is one million bytes of information. This definition has been incorporated into the International System of Quantities.
Peta- means 1,000,000,000,000,000; a Petabyte is 1,000 Terabytes. Exa- means 1,000,000,000,000,000,000; an Exabyte is 1,000 Petabytes. Zetta- means 1,000,000,000,000,000,000,000; a Zettabyte is 1,000 Exabytes. Yotta- means 1,000,000,000,000,000,000,000,000; a Yottabyte is 1,000 Zettabytes.
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.
Because English took words from both Latin and old German. "Million" comes from the Latin word "mille" which means a thousand thousand, or 1,000,000. The word billion then comes to mean a million squared, or 1,000,000,000,000 and trillion, a million cubed, or 1,000,000,000,000,000,000.
a cardinal number represented in the U.S. by 1 followed by 51 zeros, and in Great Britain by 1 followed by 96 zeros.
A vigintillion is a massive number, most commonly defined in the short scale as 1 followed by 63 zeros (106310 to the 63rd power1063), making it one thousand novemdecillion, though historically and in the long scale (used in some European countries), it could mean 1 followed by 120 zeros (1012010 to the 120th power10120). The modern standard in English-speaking countries uses the short scale, where a vigintillion is 1,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,0001 comma 000 comma 000 comma 000 comma 000 comma 000 comma 000 comma 000 comma 000 comma 000 comma 000 comma 000 comma 000 comma 000 comma 000 comma 000 comma 000 comma 000 comma 000 comma 000 comma 000 comma 0001,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000.
A unit of quantity equal to 10231 (1 followed by 231 zeros).
An unquadragintillion is equal to 10126 in the short scale, or \(10^{246}\) in the long scale by Conway and Guy's naming system and Jonathan Bowers system. In the long scale which is commonly used in France and Germany, \(10^{126}\) is called unvigintillion. 10126 was called kathana in. Pali.
