title: 'Problem 34: Digit factorials'
---
## Description
145 is a curious number, as 1! + 4! + 5! = 1 + 24 + 120 = 145.
Find the numbers and the sum of the 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.
## Instructions
## Tests
```yml
tests:
- text: 'digitFactorial() should return { sum: 40730, numbers: [145, 40585] }.'
testString: "assert.deepEqual(digitFactorial(), { sum: 40730, numbers: [145, 40585] }, 'digitFactorial() should return { sum: 40730, numbers: [145, 40585] }.');"
```
## Challenge Seed
```js
function digitFactorial() {
// Good luck!
var sum = 0;
var numbers = [];
return { sum, numbers };
}
digitFactorial();
```
