145 is a curious number, as 1! + 4! + 5! = 1 + 24 + 120 = 145.

Find the sum of all numbers which are equal to the sum of the factorial of

their digits.

Note: as 1! = 1 and 2! = 2 are not sums they are not included.

Solution:

The critical problem is finding an upper bound. This is the reasoning behind

my limit:

9! is the maximum value for any one digit

9! < 7 digits

9! * 7 is the upper bound
