C7E 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 numberC7E:

C16 = 11002

716 = 01112

E16 = 11102

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: 110 001 111 110

With Zeros: 110 001 111 110

Convert each group of binary digits to its octal equivalent:

1102 = 68

0012 = 18

1112 = 78

1102 = 68
