A prime number (or prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself. By Euclid's theorem , there are an infinite number of prime numbers. Subsets of the prime numbers may be generated with various formulas for primes .
A list of articles about numbers (not about numerals). Topics include powers of ten, notable integers, prime and cardinal numbers, and the myriad system.
A factorial x! is the product of all numbers from 1 to x. The first: 1, 2, 6, 24, 120, 720, 5040, 40320, 362880, 3628800, 39916800, 479001600 (sequence A000142 in the OEIS). 0! = 1 is sometimes included. A k-smooth number (for a natural number k) has its prime factors ≤ k (so it is also j-smooth for any j > k).
List of Mersenne primes and perfect numbers. Mersenne primes and perfect numbers are two deeply interlinked types of natural numbers in number theory. Mersenne primes, named after the friar Marin Mersenne, are prime numbers that can be expressed as 2p − 1 for some positive integer p. For example, 3 is a Mersenne prime as it is a prime number ...
3333, 4444 and 6666 have totients of 2000, 1111 and 2222 have a totient of 1000. In the list of composite numbers, 7777 is very nearly the composite index of 8888: 8886 is the 7779th composite number. [ 22 ] Also, [ 16 ] 5000 has a totient value of 2000, as does 5050 = 2025 + 3025 = 45 2 + 55 2, where.
10,000: a myriad (a hundred hundred), commonly used in the sense of an indefinite very high number. 100,000: a lakh (a hundred thousand), in Indian English. 10,000,000: a crore (a hundred lakh), in Indian English and written as 100,00,000. 10 100: googol (1 followed by 100 zeros), used in mathematics.
The tables below list all of the divisors of the numbers 1 to 1000. A divisor of an integer n is an integer m, for which n / m is again an integer (which is necessarily also a divisor of n). For example, 3 is a divisor of 21, since 21/7 = 3 (and therefore 7 is also a divisor of 21). If m is a divisor of n, then so is − m.
This is a list of all articles about natural numbers from 1 to 10,000. Red links are included to make it clearly visible which articles exist and which do not. Existing articles can either be articles with content, or redirects .
