 Think about the number 371.  The total number of digits is 3. Now, for each digit, put the power of 3 and then add them. It will be:

 ```python
 33 +73 +13
 3^3 +7^3 +1^3
 = 27 + 343 + 1
 = 371
 ```
 Similarly, 1634 is another Armstrong number, because the total number of digits is 4. Now, power each digit and sum them. You will get the Armstrong number.

 ```python
 =14 +64 +34 +44
 =1^4 +6^4 +3^4 +4^4
 = 1 + 1296 + 81 + 256
 = 1634
 ```
