- Take a number and let the number of digits in it be *n* - now raise every digit of the original number to power *n* - add all the resultant numbers and if you get the original number after addition, then the number is Armstrong number For example Number = 153 n = 3 { as it is a three digit number) 1┬│ + 5┬│ + 3┬│ = 1 + 125 + 27 = 153 { and as it is same as original number so 153 is armstrong number )
