# 37

It appears that any number greater than 1000 ( that can therefore be clustered/digit grouped) and that is divisible by 37 will always have 37 as a factor of it’s clustered/digit grouped result. That is amazing if you consider it. This phenomenon ONLY works for 37 as far as I know.

eg; 37 * 30 = 1110

Factors for 1110:- 1, 2, 3, 5, 6, 10, 15, 30, 37, 74, 111, 185, 222, 370, 555, 1110

Clustering for 1110:- 111. Cluster factors:- 1, 3, 37, 111

Or:- 37 *101010 = 3737370

Factors for 3737370:- 2, 3, 5, 6, 7, 10, 13, 14, 15, 21, 26, 30, 35, 37, 39, 42, 65, 70, 74, 78, 91, 105, 111, 130, 182, 185, 195, 210, 222, 259, 273, 370, 390, 455, 481, 518, 546, 555, 777, 910, 962, 1110, 1295, 1365, 1369, 1443, 1554, 2405, 2590, 2730, 2738, 2886, 3367, 3885, 4107, 4810, 6734, 6845, 7215, 7770, 8214, 9583, 10101, 13690, 14430, 16835, 17797, 19166, 20202, 20535, 28749, 33670, 35594, 41070, 47915, 50505, 53391, 57498, 88985, 95830, 101010, 106782, 124579, 143745, 177970, 249158, 266955, 287490, 373737, 533910, 622895, 747474, 1245790, 1868685
Clustering for 3737370:- 1110. Cluster factors:- 1, 2, 3, 5, 6, 10, 15, 30, 37, 74, 111, 185, 222, 370, 555, 1110

Or:- 37 * 2701 = 99937

Factors for 99937:- 1,37, 73, 1369, 2701, 99937
Clustering for 99937:- 1036. Cluster factors:- 1, 2, 4, 7, 14, 28, 37, 74, 148, 259, 518, 1036

Or:- pi (to 5 digits ie; 3.14159) *100,000 * 37 = 11623883

Factors for 11623883:- 37, 314159
Digit grouping for 11623883:- 1517. Digit grouping factors:- 37, 41

Or:- 908423 * 37 = 33611651

Factors for 33611651:- 1(star 1), 37(star 3), 59, 89, 173, 2183, 3293, 5251, 6401, 10207, 15397, 194287, 377659, 569689, 908423, 33611651

Digit grouping for 33611651:- 1295. Digit grouping result factors:- 1(star 1), 5, 7, 35, 37, 185, 259, 1295

Not sure why this is but so far it works.
