Roman numerals are a numeral system that originated in ancient Rome and remained the usual way of writing numbers throughout Europe well into the Late Middle Ages.Numbers are written with combinations of letters from the Latin alphabet, each with a fixed integer value.
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 Latin numerals are the words used to denote numbers within the Latin language. They are essentially based on their Proto-Indo-European ancestors, and the Latin cardinal numbers are largely sustained in the Romance languages.
Leonhard Euler noted 65 idoneal numbers (the most known, of only a maximum possible of two more), such that + for an integer , expressible in only one way, yields a prime power or twice a prime power.

210 is an abundant number, [1] and Harshad number. It is the product of the first four prime numbers (2, 3, 5, and 7), and thus a primorial, [2] where it is the least common multiple of these four prime numbers. 210 is the first primorial number greater than 2 which is not adjacent to 2 primes (211 is prime, but 209 is not).
1,000,000 (one million), or one thousand thousand, is the natural number following 999,999 and preceding 1,000,001. The word is derived from the early Italian millione (milione in modern Italian), from mille, "thousand", plus the augmentative suffix -one.
116 is a noncototient, meaning that there is no solution to the equation m − φ(m) = n, where φ stands for Euler's totient function. [1]116! + 1 is a factorial prime. [2] ...
