100 or one hundred (Roman numeral: C) [1] is the natural number following 99 and preceding 101.
100 is the square of 10 (in scientific notation it is written as 102). The standard SI prefix for a hundred is "hecto-".
100 is the basis of percentages (per cent meaning "per hundred" in Latin), with 100% being a full amount.
100 is a Harshad number in decimal, and also in base-four, a base in-which it is also a self-descriptive number. [2] [3]
100 is the sum of the first nine prime numbers, from 2 through 23. [4] It is also divisible by the number of primes below it, 25. [5]
100 cannot be expressed as the difference between any integer and the total of coprimes below it, making it a noncototient. [6]
100 has a reduced totient of 20, and an Euler totient of 40. [7] [8] A totient value of 100 is obtained from four numbers: 101, 125, 202, and 250.
100 can be expressed as a sum of some of its divisors, making it a semiperfect number. [9] The geometric mean of its nine divisors is 10.
100 is the sum of the cubes of the first four positive integers (100 = 13 + 23 + 33 + 43). [10] This is related by Nicomachus's theorem to the fact that 100 also equals the square of the sum of the first four positive integers: 100 = 102 = (1 + 2 + 3 + 4)2. [11]
100 = 26 + 62, thus 100 is the seventh Leyland number. [12] 100 is also the seventeenth Erdős–Woods number, and the fourth 18-gonal number. [13] [14]
The 100th prime number is 541, which returns for the Mertens function. [15] It is the 10th star number [16] (whose digit sum also adds to 10 in decimal).
There are exactly 100 prime numbers in base-ten whose digits are in strictly ascending order (e.g. 239, 2357 etc.). [17] The last such prime number is 23456789, which contains eight consecutive integers as digits.
One hundred is the atomic number of fermium, an actinide and the last of the heavy metals that can be created through neutron bombardment.
On the Celsius scale, 100 degrees is the boiling temperature of pure water at sea level.
The Kármán line lies at an altitude of 100 kilometres above the Earth's sea level and is commonly used to define the boundary between Earth's atmosphere and outer space.
Most of the world's currencies are divided into 100 subunits; for example, one euro is one hundred cents and one pound sterling is one hundred pence.
By specification, 100 euro notes feature a picture of a Rococo gateway on the obverse and a Baroque bridge on the reverse.
The U.S. hundred-dollar bill has Benjamin Franklin's portrait; the "Benjamin" is the largest U.S. bill in print. American savings bonds of $100 have Thomas Jefferson's portrait, while American $100 treasury bonds have Andrew Jackson's portrait.
One hundred is also:
10 (ten) is the even natural number following 9 and preceding 11. Ten is the base of the decimal numeral system, the most common system of denoting numbers in both spoken and written language.
222 is the natural number following 221 and preceding 223.
90 (ninety) is the natural number following 89 and preceding 91.
36 (thirty-six) is the natural number following 35 and preceding 37.
48 (forty-eight) is the natural number following 47 and preceding 49. It is one third of a gross, or four dozens.
300 is the natural number following 299 and preceding 301.
360 is the natural number following 359 and preceding 361.
400 is the natural number following 399 and preceding 401.
144 is the natural number following 143 and preceding 145.
500 is the natural number following 499 and preceding 501.
555 is the natural number following 554 and preceding 556.
700 is the natural number following 699 and preceding 701.
600 is the natural number following 599 and preceding 601.
800 is the natural number following 799 and preceding 801.
2000 is a natural number following 1999 and preceding 2001.
135 is the natural number following 134 and preceding 136.
168 is the natural number following 167 and preceding 169.
240 is the natural number following 239 and preceding 241.
744 is the natural number following 743 and preceding 745.
888 is the natural number following 887 and preceding 889.
