Wednesday 28 December

Today is 362 day of the year.
362 = 2 x 181, which makes it semiprime.

The sum of the squares of the digits of 362 is 49,
i.e. (3 x 3) + (6 x 6) + (2 x 2) = 9 + 36 + 4 = 49
Repeating this exercise with the resulting number 49 gives
16 + 81 = 97
Then again with 97 and continuing;
81 + 49 = 130
1 + 9 + 0 = 10
1 + 0 = 1
As the number 1 has been reached then this means that 362 is a happy number.
