# Solution to Project Euler Problem 30: Digit fifth powers - Surprisingly there are only three numbers that can be written as the sum of fourth powers of their digits: As 1 = 1^4 is not a sum it is not included. The sum of these numbers is 1634 + 8208 + 9474 = 19316. Find the sum of all the numbers that can be written as the sum of fifth powers of their digits.

**Topic:** Project Euler Problem 30: Digit fifth powers.

**Difficulty:** Easy.

**Objective:** Surprisingly there are only three numbers that can be written as the sum of fourth powers of their digits:

1634 = 1^{4} + 6^{4} + 3^{4} + 4^{4}

8208 = 8^{4} + 2^{4} + 0^{4} + 8^{4}

9474 = 9^{4} + 4^{4} + 7^{4} + 4^{4}

As 1 = 1^{4} is not a sum it is not included.

The sum of these numbers is 1634 + 8208 + 9474 = 19316.

Find the sum of all the numbers that can be written as the sum of fifth powers of their digits.

**Input:** None.

**Expected Output:** 443839.
