15C Hex in Octal

Converting a hexadecimal number to octal without a calculator involves first converting the hexadecimal number to binary, then grouping the binary digits into groups of three, and finally converting each group to its octal equivalent. Here's a step-by-step guide for hexadecimal number15C:

116 = 00012

516 = 01012

C16 = 11002

Group the binary digits into groups of three, starting from the right. If the last group has fewer than three digits, pad it with zeros on the left.

Binary: 000 101 011 100

With Zeros: 000 101 011 100

Convert each group of binary digits to its octal equivalent:

0002 = 08

1012 = 58

0112 = 38

1002 = 48
