This is a list of articles about prime numbers.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.
The first: 4, 8, 9, 16, 25, 27, 32, 36, 49, 64, 81, 100 (sequence A001597 in the OEIS). 1 is sometimes included. A powerful number (also called squareful ) has multiplicity above 1 for all prime factors.
Since it is possible to find sequences of 36 consecutive integers such that each inner member shares a factor with either the first or the last member, 36 is an Erdős–Woods number. [11] The sum of the integers from 1 to 36 is 666 (see number of the beast). 36 is also a Tridecagonal number. [12]
The first five of these numbers – 3, 5, 17, 257, and 65,537 – are prime, [172] but is composite and so are all other Fermat numbers that have been verified as of 2017. [173] A regular n {\displaystyle n} -gon is constructible using straightedge and compass if and only if the odd prime factors of n {\displaystyle n} (if any) are distinct ...
The first number in the list is 2; cross out every 2nd number in the list after 2 by counting up from 2 in increments of 2 (these will be all the multiples of 2 in ...
1060 = sum of the first twenty-five primes from 2 through 97 (the number of primes less than 100), [56] and sixth sum of 10 consecutive primes, starting with 23 through 131. [ 57 ] 1061 = emirp , twin prime with 1063 , number of prime numbers between 1000 and 10000 (or, number of four-digit primes in decimal representation) [ 58 ]

In mathematics, a multiple is the product of any quantity and an integer. [1] In other words, for the quantities a and b, it can be said that b is a multiple of a if b = na for some integer n, which is called the multiplier. If a is not zero, this is equivalent to saying that / is an integer.
