This section illustrates several systems for naming large numbers, and shows how they can be extended past vigintillion . Traditional British usage assigned new names for each power of one million (the long scale ): 1,000,000 = 1 million; 1,000,0002 = 1 billion; 1,000,0003 = 1 trillion; and so on. It was adapted from French usage, and is ...
Other large numbers regarding length and time are found in astronomy and cosmology.For example, the current Big Bang model suggests that the universe is 13.8 billion years (4.355 × 10 17 seconds) old, and that the observable universe is 93 billion light years across (8.8 × 10 26 metres), and contains about 5 × 10 22 stars, organized into around 125 billion (1.25 × 10 11) galaxies ...
The ultimate in large numbers was, until recently, the concept of infinity, a number defined by being greater than any finite number, and used in the mathematical theory of limits. However, since the 19th century, mathematicians have studied transfinite numbers , numbers which are not only greater than any finite number, but also, from the ...
A list of articles about numbers (not about numerals). Topics include powers of ten, notable integers, prime and cardinal numbers, and the myriad system.
This list includes estimates of all deaths which were directly or indirectly caused by genocides that are recognised in significant scholarship as genocides. It excludes mass killings which have not been explicitly defined as genocidal, but called mass murder, crimes against humanity, politicide, classicide, or war crimes, such as the Thirty Years' War (4.5 to 8 million deaths), Japanese war ...
Large numbers in mathematics may be large and finite, like a googol, or the large infinite cardinal numbers which have a subcategory here. Subcategories This category has the following 2 subcategories, out of 2 total.
The largest known prime number is 2 82,589,933 − 1, a number which has 24,862,048 digits when written in base 10. It was found via a computer volunteered by Patrick Laroche of the Great Internet Mersenne Prime Search (GIMPS) in 2018.

Forty-two (42) is the sixth pronic number [ 1] and the eighth abundant number, [ 2] with an abundance of 12, [ 3] equal to the average of its eight divisors as an arithmetic number. [ 4][ 5] Its prime factorization makes it the second sphenic number, and also the second of the form . [ 6] 42 is the aliquot sum of 30, [ 7] the smallest sphenic ...
