2D18 hexadecimal to octal

Here we will show you how to convert the hexadecimal number 2D18 to an octal number. First note that the hexadecimal number system has sixteen different digits (0 1 2 3 4 5 6 7 8 9 A B C D E F) and the octal number system has only eight different digits (0 1 2 3 4 5 6 7).

The four steps used to convert 2D18 from hexadecimal to octal are explained below.

Step 1)
Multiply the last digit in 2D18 by 16⁰, multiply the second to last digit in 2D18 by 16¹, multiply the third to last digit in 2D18 by 16², multiply the fourth to last digit in 2D18 by 16³, and so on, until all the digits are used.

8 × 16⁰ = 8
1 × 16¹ = 16
D × 16² = 3328
2 × 16³ = 8192

Remember that the hexadecimal number system has sixteen different digits, so when doing the above calculation, we use the following values if applicable: A=10, B=11, C=12, D=13, E=14, and F=15.

Step 2)
Next, we add up all the products we got from Step 1, like this:

8 + 16 + 3328 + 8192 = 11544

Step 3)
Now we divide the sum from Step 2 by 8. Put the remainder aside. Then divide the whole part by 8 again, and put the remainder aside again. Keep doing this until the whole part is 0.

11544 ÷ 8 = 1443 with 0 remainder
1443 ÷ 8 = 180 with 3 remainder
180 ÷ 8 = 22 with 4 remainder
22 ÷ 8 = 2 with 6 remainder
2 ÷ 8 = 0 with 2 remainder

Step 4)
In the final step, we take the remainders from Step 3 and put them together in reverse order to get our answer to 2D18 hexadecimal to octal:

2D18 hexadecimal = 26430 octal
