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 numberA78:

A16 = 10102

716 = 01112

816 = 10002

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: 101 001 111 000

Convert each group of binary digits to its octal equivalent:
