13643 octal to binary

Here we will show you how to convert the octal number 13643 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 13643 from octal to binary are explained below.

Step 1)
Multiply the last digit in 13643 by 8⁰, multiply the second to last digit in 13643 by 8¹, multiply the third to last digit in 13643 by 8², multiply the fourth to last digit in 13643 by 8³, and so on, until all the digits are used:

3 × 8⁰ = 3
4 × 8¹ = 32
6 × 8² = 384
3 × 8³ = 1536
1 × 8⁴ = 4096

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

3 + 32 + 384 + 1536 + 4096 = 6051

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.

6051 ÷ 2 = 3025 with 1 remainder
3025 ÷ 2 = 1512 with 1 remainder
1512 ÷ 2 = 756 with 0 remainder
756 ÷ 2 = 378 with 0 remainder
378 ÷ 2 = 189 with 0 remainder
189 ÷ 2 = 94 with 1 remainder
94 ÷ 2 = 47 with 0 remainder
47 ÷ 2 = 23 with 1 remainder
23 ÷ 2 = 11 with 1 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 13643 octal to binary:

13643 octal = 1011110100011 binary
