65A9 hexadecimal to octal

Here we will show you how to convert the hexadecimal number 65A9 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 65A9 from hexadecimal to octal are explained below.

Step 1)
Multiply the last digit in 65A9 by 16⁰, multiply the second to last digit in 65A9 by 16¹, multiply the third to last digit in 65A9 by 16², multiply the fourth to last digit in 65A9 by 16³, and so on, until all the digits are used.

9 × 16⁰ = 9
A × 16¹ = 160
5 × 16² = 1280
6 × 16³ = 24576

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:

9 + 160 + 1280 + 24576 = 26025

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.

26025 ÷ 8 = 3253 with 1 remainder
3253 ÷ 8 = 406 with 5 remainder
406 ÷ 8 = 50 with 6 remainder
50 ÷ 8 = 6 with 2 remainder
6 ÷ 8 = 0 with 6 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 65A9 hexadecimal to octal:

65A9 hexadecimal = 62651 octal
