8EF 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 number8EF:

816 = 10002

E16 = 11102

F16 = 11112

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: 100 011 101 111

With Zeros: 100 011 101 111

Convert each group of binary digits to its octal equivalent:

1002 = 48

0112 = 38

1012 = 58

1112 = 78
