F91A hexadecimal to octal

Here we will show you how to convert the hexadecimal number F91A 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 F91A from hexadecimal to octal are explained below.

Step 1)
Multiply the last digit in F91A by 16⁰, multiply the second to last digit in F91A by 16¹, multiply the third to last digit in F91A by 16², multiply the fourth to last digit in F91A by 16³, and so on, until all the digits are used.

A × 16⁰ = 10
1 × 16¹ = 16
9 × 16² = 2304
F × 16³ = 61440

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 + 16 + 2304 + 61440 = 63770

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.

63770 ÷ 8 = 7971 with 2 remainder
7971 ÷ 8 = 996 with 3 remainder
996 ÷ 8 = 124 with 4 remainder
124 ÷ 8 = 15 with 4 remainder
15 ÷ 8 = 1 with 7 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 F91A hexadecimal to octal:

F91A hexadecimal = 174432 octal
