D78F hexadecimal to octal

Here we will show you how to convert the hexadecimal number D78F 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 D78F from hexadecimal to octal are explained below.

Step 1)
Multiply the last digit in D78F by 16⁰, multiply the second to last digit in D78F by 16¹, multiply the third to last digit in D78F by 16², multiply the fourth to last digit in D78F by 16³, and so on, until all the digits are used.

F × 16⁰ = 15
8 × 16¹ = 128
7 × 16² = 1792
D × 16³ = 53248

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:

15 + 128 + 1792 + 53248 = 55183

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.

55183 ÷ 8 = 6897 with 7 remainder
6897 ÷ 8 = 862 with 1 remainder
862 ÷ 8 = 107 with 6 remainder
107 ÷ 8 = 13 with 3 remainder
13 ÷ 8 = 1 with 5 remainder
1 ÷ 8 = 0 with 1 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 D78F hexadecimal to octal:

D78F hexadecimal = 153617 octal
