BC45 hexadecimal to octal

Here we will show you how to convert the hexadecimal number BC45 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 BC45 from hexadecimal to octal are explained below.

Step 1)
Multiply the last digit in BC45 by 16⁰, multiply the second to last digit in BC45 by 16¹, multiply the third to last digit in BC45 by 16², multiply the fourth to last digit in BC45 by 16³, and so on, until all the digits are used.

5 × 16⁰ = 5
4 × 16¹ = 64
C × 16² = 3072
B × 16³ = 45056

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:

5 + 64 + 3072 + 45056 = 48197

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.

48197 ÷ 8 = 6024 with 5 remainder
6024 ÷ 8 = 753 with 0 remainder
753 ÷ 8 = 94 with 1 remainder
94 ÷ 8 = 11 with 6 remainder
11 ÷ 8 = 1 with 3 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 BC45 hexadecimal to octal:

BC45 hexadecimal = 136105 octal
