Write 12,767 in base sixteen.

  • math -

    Last digit:

    12,767 Mod 16 = 15 = F

    Subtract last digit and divide by 16:

    (12,767 - 15 )/16 = 797

    The last digit of this is:

    797 Mod 16 = 13 = D

    Subtract this digit and divide by 16:

    (797 - 13)/16 = 49

    Last digit of this is:

    49 Mod 16 = 1

    Subtract this digit and divide by 16:

    (49 - 1)/16 = 3

    So, the number in base 16 is 31DF
