How do you convert a decimal number to octal number?

Answer 1

One method:

Take the decimal number, divide by 8.

The remainder of the division will be the least significant (rightmost) digit of the octal number.

Take the quotient from the previous step, divide it by 8. The remainder will be the next digit of the octal number (going right to left).

Repeat until the quotient is 0.

Example: Convert 300 to octal.

300/8 = 37 Remainder 4.

37/8 = 4 remainder 5.

4/8 = 0 remainder 4.

So the octal number is 454.

You can test this by calculating:

4 * 8^2 + 5 * 8^1 + 4 * 8^0

= 4*64 + 5*8 + 4

= 256 + 40 + 4 = 300.
