    Hello, dblbac!

    Convert FAB4_{16} to octal.
    There is a trick we can use . . .


    We know that: . FAB4_{16} \;=\;[15]\,[10]\,[11]\,[4]

    Convert to binary: . [1111]\,[1010]\,[1011]\,[0100]

    Remove the brackets: . 1111101010110100

    Regroup "by threes": . [1]\,[111]\,[101]\,[010]\,[110]\,[100]

    Covert to octal: . . . . . 1\quad7\quad\;\;\:5\quad\;\;2\quad\;\;\;6\quad\;\;  4


    Answer: . 175264_8
