Algunos números naturales que tienen k dígitos, son iguales a la suma de cada uno de sus dígitos elevados a la potencia
k. Por ejemplo, 370 es un número que cumple esta condición, porque k = 3, entonces:
370 = 3 + 7 + 0
370 = 27 + 343 + 0
370 = 370
¿Cuál de los siguientes números cumple también esta condición?

Answer:
from the Euclids division algorithm......
370 = 3 + 7 + 0
370 = 27 + 343 + 0
370 = 370.....
hence , 27 will be the HCF.

Dado:
Some natural numbers that have k digits are equal to the sum of each of their digits raised to the power k. For example, 370 is a number that meets this condition, because k = 3, then:
370 = 3 + 7 + 0 370 = 27 + 343 + 0 370 = 370

Which of the following numbers also meets this condition?
Solución:
407 = 4 + 0 + 7
407 = 4³ + 0³ + 7³
407 = 64 + 0 + 343
407 = 407
371 = 3 + 7 + 1
371 = 3³ + 7³ + 1³
371 = 27 + 343 + 1
371 = 371
