13021 octal to binary

Here we will show you how to convert the octal number 13021 to a binary number. First note that the octal number system has eight different digits (0 1 2 3 4 5 6 7) and the binary number system has only two different digits (0 and 1).

The four steps used to convert 13021 from octal to binary are explained below.

Step 1)
Multiply the last digit in 13021 by 8⁰, multiply the second to last digit in 13021 by 8¹, multiply the third to last digit in 13021 by 8², multiply the fourth to last digit in 13021 by 8³, and so on, until all the digits are used:

1 × 8⁰ = 1
2 × 8¹ = 16
0 × 8² = 0
3 × 8³ = 1536
1 × 8⁴ = 4096

Step 2)
Next, we add up all the products we got from Step 1, like this:

1 + 16 + 0 + 1536 + 4096 = 5649

Step 3)
Now we divide the sum from Step 2 by 2. Put the remainder aside. Then divide the whole part by 2 again, and put the remainder aside again. Keep doing this until the whole part is 0.

5649 ÷ 2 = 2824 with 1 remainder
2824 ÷ 2 = 1412 with 0 remainder
1412 ÷ 2 = 706 with 0 remainder
706 ÷ 2 = 353 with 0 remainder
353 ÷ 2 = 176 with 1 remainder
176 ÷ 2 = 88 with 0 remainder
88 ÷ 2 = 44 with 0 remainder
44 ÷ 2 = 22 with 0 remainder
22 ÷ 2 = 11 with 0 remainder
11 ÷ 2 = 5 with 1 remainder
5 ÷ 2 = 2 with 1 remainder
2 ÷ 2 = 1 with 0 remainder
1 ÷ 2 = 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 13021 octal to binary:

13021 octal = 1011000010001 binary
