Stuck on a homework question

Convert the signed hex number C59D to Binary/Octal/Decimal

Binarys easy = 1100 0101 1001 1101
Decimal i got = -14947
but I am not sure about octal, I am getting 142635, which can't be right because its a positive value, the answer should be a (signed) neg number between 400000-777777

any ideas?

Find the two's complement form of your binary number, which is 0011 1010 0110 0011. Divide into groups of three binary digits, starting on the right. I get 35143 (really, -35145).
