An integer is determined to be even if it is divisible by 2. For integers written in a numeral system based on an even number such as decimal, divisibility by 2 is easily tested by merely looking at the last digit. If it is even, then the whole number is even. When written in the decimal system, all multiples of 2 will end in 0, 2, 4, 6, or 8.
The number two is the smallest, and only even, prime number. As the smallest prime number, two is also the smallest non-zero pronic number, and the only pronic prime. Every integer greater than 1 will have at least two distinct factors; by definition, a prime number only has two distinct factors (itself and 1). Therefore, the number-of-divisors fun...
The numbers two and three are the only two prime numbers that are also consecutive integers. Two is the first prime number that does not have a proper twin prime with a difference two, while three is the first such prime number to have a twin prime, five. In consequence, three and five encase four in-between, which is the square of two, 2 2 {\displ...
Regarding regular polygonsin two dimensions: 1. The equilateral triangle has the smallest ratio of the circumradius R {\displaystyle R} to the inradius r {\displaystyle r} of any triangle by Euler's inequality, with R r = 2. {\displaystyle {\tfrac {R}{r}}=2.} 1. The long diagonal of a regular hexagon is of length 2 when its sides are of unit length...
