A natural number (i.e. 1, 2, 3, 4, 5, 6, etc.) is called a prime number (or a prime) if it has exactly two positive divisors, 1 and the number itself. Natural numbers greater than 1 that are not prime are called composite.

The first 1X5 prime numbers (all the prime numbers less than 1000) are:

2, 3, 5, 7, E, 11, 15, 17, 1E, 25, 27, 31, 35, 37, 3E, 45, 4E, 51, 57, 5E, 61, 67, 6E, 75, 81, 85, 87, 8E, 91, 95, X7, XE, E5, E7, 105, 107, 111, 117, 11E, 125, 12E, 131, 13E, 141, 145, 147, 157, 167, 16E, 171, 175, 17E, 181, 18E, 195, 19E, 1X5, 1X7, 1E1, 1E5, 1E7, 205, 217, 21E, 221, 225, 237, 241, 24E, 251, 255, 25E, 267, 271, 277, 27E, 285, 291, 295, 2X1, 2XE, 2E1, 2EE, 301, 307, 30E, 315, 321, 325, 327, 32E, 33E, 347, 34E, 357, 35E, 365, 375, 377, 391, 397, 3X5, 3XE, 3E5, 3E7, 401, 40E, 415, 41E, 421, 427, 431, 435, 437, 447, 455, 457, 45E, 465, 46E, 471, 481, 485, 48E, 497, 4X5, 4E1, 4EE, 507, 511, 517, 51E, 527, 531, 535, 541, 545, 557, 565, 575, 577, 585, 587, 58E, 591, 59E, 5E1, 5E5, 5E7, 5EE, 611, 615, 617, 61E, 637, 63E, 647, 655, 661, 665, 66E, 675, 687, 68E, 695, 69E, 6X7, 6E1, 701, 705, 70E, 711, 71E, 721, 727, 735, 737, 745, 747, 751, 767, 76E, 771, 775, 77E, 785, 791, 797, 7X1, 7EE, 801, 80E, 817, 825, 82E, 835, 841, 851, 855, 85E, 865, 867, 871, 881, 88E, 8X5, 8X7, 8XE, 8E5, 8E7, 901, 905, 907, 90E, 91E, 921, 927, 955, 95E, 965, 971, 987, 995, 9X7, 9XE, 9E1, 9E5, 9EE, X07, X0E, X11, X17, X27, X35, X37, X3E, X41, X45, X4E, X5E, X6E, X77, X87, X91, X95, X9E, XX7, XXE, XE7, XEE, E11, E15, E1E, E21, E25, E2E, E31, E37, E45, E61, E67, E6E, E71, E91, E95, E97, EX5, EE5, EE7

Except 2 and 3, all primes end with 1, 5, 7 or E. The first k such that all of 10k, 10k + 1, 10k + 2, ..., 10k + E are composite is 38, i.e. all of 380, 381, 382, ..., 38E are composite. (numbers k such that all of 10k, 10k + 1, 10k + 2, ..., 10k + E are composite are 38, 5X, 60, 62, 89, 93, 94, E0, E5, E8, ...)

The maximal gaps of the primes less than 1000 is (927, 955), the gap (the difference of these two numbers) is 2X (i.e. there are 29 consecutive composites between 927 and 955).

The density of primes end with 1 is a relatively low (< 1/4), but the density of primes end with 5, 7 and E are nearly equal (all are a little more than 1/4). (i.e. for a given natural number N, the number of primes end with 1 less than N is usually smaller than the number of primes end with 5 (or 7, or E) less than N) e.g. For all 1426 primes < 10000, there are 3E8 primes (2E.3%) end with 1, 410 primes (30.3%) end with 5, 412 primes (30.5%) end with 7, 406 primes (2E.E%) end with E. It is conjectured that for every natural number N β‰₯ 10, the number of primes end with 1 less than N is smaller than the number of primes end with 5 (or 7, or E) less than N. (Note: the percentage in this section are also in dozenal, i.e. 20% means 0.2 or 20/100 = 1/6, 36% means 0.36 or 36/100 = 7/20, 58.7% means 0.587 or 587/1000)

13665 is the smallest prime p such that the number of primes end with 1 or 5 ≀ p is more than the number of primes end with 3, 7 or E ≀ p (i.e. congruent to 1 or 3 mod 4, see [1], of course, 3 is the only prime ends with 3). Besides, 9X03693X831 is the smallest prime p such that the number of primes end with 1 or 7 ≀ p is more than the number of primes end with 2, 5 or E ≀ p (i.e. congruent to 1 or 2 mod 3, see [2], of course, 2 is the only prime ends with 2). Besides, 2E69E is the smallest prime p such that the number of primes end with 1 or E ≀ p is more than the number of primes end with 5 or 7 ≀ p (of course, 2 is the only prime ends with 2, and 3 is the only prime ends with 3). Question: What is the smallest prime p such that the number of primes end with 1 ≀ p is more than the number of primes end with d ≀ p for at least one of d = 5, 7 or E?

All squares of primes (except 2 and 3) end with 1.

There are 2X primes between 1 and 100, 23 primes between 101 and 200, 1X primes between 201 and 300, 1X primes between 301 and 400, 1E primes between 401 and 500, 1X primes between 501 and 600, 16 primes between 601 and 700, 1X primes between 701 and 800, 18 primes between 801 and 900, 16 primes between 901 and X00, 1X primes between X01 and E00, 17 primes between E01 and 1000.

There are about N/ln(N) primes less than N, where ln is the natural logarithm, i.e. the logarithm with base e = 2.875236069821... (see prime number theorem), thus there are about

primes less than 10n (i.e. with at most n digits), and ln(10) = 2.599E035E8169...

The twin prime pairs below 100 are (3, 5), (5, 7), (E, 11), (15, 17), (25, 27), (35, 37), (4E, 51), (5E, 61), (85, 87), (8E, 91), (E5, E7), and there are only 47 twin prime pairs below 1000. Except (3, 5), all twin prime pairs end with (5, 7) or (E, 1), and it is conjectured that the density of them are the same.

Primes sorted by the last digit

Gaussian primes are primes in the ring

, Eisenstein primes are primes in the ring

.

  • The primes end with 1 are neither Gaussian primes nor Eisenstein primes.
  • The primes end with 5 (also the prime 2) are Eisenstein primes, but not Gaussian primes.
  • The primes end with 7 (also the prime 3) are Gaussian primes, but not Eisenstein primes.
  • The primes end with E are both Gaussian primes and Eisenstein primes.

The primes end with 1, 5, 7 and E are called 1-primes, 5-primes, 7-primes and E-primes, respectively.
