Am I stupid as fuck or is there something up with this number?
Re occuring either integers, divisibles, multiplications, sums, denominations, decimals, primes etc. that are relative to 7 ARE:
1(one) 2 (two), 3 (three), 4(four) and 10(ten) (maybe more but Im a stupid)
Factors of 7 = 1 & 7
[3, 6, 9, show some relatability but not enough to confirm significant connection.. yet]
7 is a prime number because 2, 3, 4, 5 or 6
cant divide 7 evenly
(Cruisenaire rods)
7=1x7(prime)
7=3x2+1(composite)
7=4x1+3(composite)
7=5x1+2(composite)
7=6x1+1(composite)
7=7x1(prime)
7 is the 4th prime number
17 is the 7th prime number
7 is a Mersenne Prime number
There are 47 Mersenne Prime numbers
47 is a PRIME number (divisors are 1 and 47)
(4th prime is 7)
(4th SAFE prime is 47)
With the exception of 7, there are no Mersenne primes that are also safe primes.
The exponents n which give Mersenne primes are 2, 3, 5, 7, 13, 17, 19, 31, ...
(seq. A000043)
and the resulting Mersenne primes are 3, 7, 31, 127, 8191, 131071, 524287, 2147483647
Seven is the lowest natural number that cannot be represented as the sum of the squares of three integers. (See Lagrange's four-square theorem)
Seven is the aliquot sum of one number, the cubic number 8 and is the base of the 7-aliquot tree.
7 is the only number D for which the equation 2n ? D = x2 has more than two solutions for n and x natural. In particular, the equation 2n ? 7 = x2 is known as the Ramanujan–Nagell equation.
7 is the only dimension, besides the familiar 3, in which a vector cross product can be defined.
7 is the lowest dimension of a known exotic sphere, although there may exist as yet unknown exotic smooth structures on the 4-dimensional sphere.
999,999 divided by 7 is exactly 142,857. Therefore, when a vulgar fraction with 7 in the denominator is converted to a decimal expansion,
the result has the same six-digit repeating sequence after the decimal point, but the sequence can start with any of those six digits.
