Example

Divisors of 320 are {1, 2, 10, 13, 20, 32, 130, 320} in base 4; each digit appears 4 times, so a(1) = 4.
Divisors of 20132 are {1, 2, 10033, 20132} in base 4; each digit appears 3 times, so a(2) = 3.
Divisors of 21320 are {1, 2, 10, 20, 1033, 2132, 10330, 21320} in base 4; each digit appears 6 times, so a(3) = 6
