7ECB hexadecimal to octal

Here we will show you how to convert the hexadecimal number 7ECB 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 7ECB from hexadecimal to octal are explained below.

Step 1)
Multiply the last digit in 7ECB by 16⁰, multiply the second to last digit in 7ECB by 16¹, multiply the third to last digit in 7ECB by 16², multiply the fourth to last digit in 7ECB by 16³, and so on, until all the digits are used.

B × 16⁰ = 11
C × 16¹ = 192
E × 16² = 3584
7 × 16³ = 28672

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:

11 + 192 + 3584 + 28672 = 32459

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.

32459 ÷ 8 = 4057 with 3 remainder
4057 ÷ 8 = 507 with 1 remainder
507 ÷ 8 = 63 with 3 remainder
63 ÷ 8 = 7 with 7 remainder
7 ÷ 8 = 0 with 7 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 7ECB hexadecimal to octal:

7ECB hexadecimal = 77313 octal
