51DF hexadecimal to octal

Here we will show you how to convert the hexadecimal number 51DF 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 51DF from hexadecimal to octal are explained below.

Step 1)
Multiply the last digit in 51DF by 16⁰, multiply the second to last digit in 51DF by 16¹, multiply the third to last digit in 51DF by 16², multiply the fourth to last digit in 51DF by 16³, and so on, until all the digits are used.

F × 16⁰ = 15
D × 16¹ = 208
1 × 16² = 256
5 × 16³ = 20480

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 + 208 + 256 + 20480 = 20959

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.

20959 ÷ 8 = 2619 with 7 remainder
2619 ÷ 8 = 327 with 3 remainder
327 ÷ 8 = 40 with 7 remainder
40 ÷ 8 = 5 with 0 remainder
5 ÷ 8 = 0 with 5 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 51DF hexadecimal to octal:

51DF hexadecimal = 50737 octal
