Factorization ${\ displaystyle 2 ^ {24} \ cdot 5 ^ {24}}$
Divider All numbers that are neither divisible by nor by a prime number other than 2 and 5 (see running text). ${\ displaystyle 2 ^ {25}}$${\ displaystyle 5 ^ {25}}$

The word Quadrillion is the number word for the fourth power of a million, hence the prefix "quad". So it's the number . There is no common abbreviation. In contrast to the lower case number words like one hundred and one thousand , Quadrillion is a noun and is capitalized. ${\ displaystyle 1,000,000 ^ {4} = 10 ^ {6 \ cdot 4} = 10 ^ {24} = 1,000,000,000,000,000,000,000,000}$

The meaning of the numeral “Quadrillion” differs depending on the language. In German and French it stands for 10 24 . In US English, "quadrillion" stands for 10 15 , which in German means billiards . The Quadrillion is called "septillion" in English. In British English, “quadrillion” is used for both 10 15 and traditionally 10 24 due to US influence .

## Math

### Divider

Factoring is . This results in so ways a power of two ( up ) with a power of five ( to multiply). The number 1,000,000,000,000,000,000 has exactly the following 625 factors: ${\ displaystyle 2 ^ {24} \ cdot 5 ^ {24}}$${\ displaystyle (24 + 1) \ cdot (24 + 1)}$${\ displaystyle 25 \ cdot 25 = 625}$${\ displaystyle 2 ^ {0}}$${\ displaystyle 2 ^ {24}}$${\ displaystyle 5 ^ {0}}$${\ displaystyle 5 ^ {24}}$

## Unit of measure prefixes

### SI prefix

When referring to units of measurement , one denotes the quadrillionfold of the unit of measurement with the prefix Yotta (abbreviated: Y), whereas the quadrillionth part (10 −24 ) is denoted by yocto (abbreviated: y). For example, a yoctometer (ym) is one quadrillionth of a meter (10 −24 m).

### Binary prefix

Even when referring to the unit of measurement byte in computer science, the term yottabyte (abbreviated: YB) is understood to mean exactly one quadrillion bytes. That is 10 24 bytes and not 2 80 = 1024 81,208,925,819,614,629,174,706,176 bytes, which exceeds one quadrillion bytes by approx. 20.89% . Today the designation Yobibyte (YiB) is suggested for naming 2 80 bytes ; yobi (Yi) is a binary prefix while Yotta (Y) is a decimal prefix.
