Here we will show you how to convert the hexadecimal number 12FA 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 12FA from hexadecimal to octal are explained below.
Step 1)
Multiply the last digit in 12FA by 16⁰, multiply the second to last digit in 12FA by 16¹, multiply the third to last digit in 12FA by 16², multiply the fourth to last digit in 12FA by 16³, and so on, until all the digits are used.
A × 16⁰ = 10
F × 16¹ = 240
2 × 16² = 512
1 × 16³ = 4096
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:
10 + 240 + 512 + 4096 = 4858
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.
4858 ÷ 8 = 607 with 2 remainder
607 ÷ 8 = 75 with 7 remainder
75 ÷ 8 = 9 with 3 remainder
9 ÷ 8 = 1 with 1 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 12FA hexadecimal to octal:
12FA hexadecimal = 11372 octal
