E87 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 numberE87:

E16 = 11102

816 = 10002

716 = 01112

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: 111 010 000 111

With Zeros: 111 010 000 111

Convert each group of binary digits to its octal equivalent:

1112 = 78

0102 = 28

0002 = 08

1112 = 78
