In number theory, a happy number is a number which eventually reaches 1 when consecutively replaced by the sum of the square of each digit. For example, 19 is a happy number because,
12 + 92 = 82
82 + 22 = 68
62 + 82 = 100
12 + 02 + 02 = 1
- The 19th Happy Prime is 379
- The 379th Lonely Gaussian Prime is 9127
- The number of digits of 19th Mersenne Prime is 1281
- 1281 = 3 × 7 × 61
- The indices of these Prime factors are 2 4 18.
- 2418th Gaussian Prime is 46511
- 46511 is the 790th Happy Prime
- 790 is the number of verses containing the wordGod in 9:127.
