Problem 56418. Easy Sequences 78: Trailing Zeros of Factorial Numbers at any Base
Given an integer n and a number base b, write a function that calculates the number of trailing zeros of the factorial of n when written in base-b.
For example, for and , the function should return 5, because:
>> dec2base(factorial(15),4)
>> '103001313131311200000'
For and , the function should return 4.
>> dec2base(factorial(10),12)
>> '1270000'
