11643 octal to binary

Here we will show you how to convert the octal number 11643 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 11643 from octal to binary are explained below.

Step 1)
Multiply the last digit in 11643 by 8⁰, multiply the second to last digit in 11643 by 8¹, multiply the third to last digit in 11643 by 8², multiply the fourth to last digit in 11643 by 8³, and so on, until all the digits are used:

3 × 8⁰ = 3
4 × 8¹ = 32
6 × 8² = 384
1 × 8³ = 512
1 × 8⁴ = 4096

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

3 + 32 + 384 + 512 + 4096 = 5027

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.

5027 ÷ 2 = 2513 with 1 remainder
2513 ÷ 2 = 1256 with 1 remainder
1256 ÷ 2 = 628 with 0 remainder
628 ÷ 2 = 314 with 0 remainder
314 ÷ 2 = 157 with 0 remainder
157 ÷ 2 = 78 with 1 remainder
78 ÷ 2 = 39 with 0 remainder
39 ÷ 2 = 19 with 1 remainder
19 ÷ 2 = 9 with 1 remainder
9 ÷ 2 = 4 with 1 remainder
4 ÷ 2 = 2 with 0 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 11643 octal to binary:

11643 octal = 1001110100011 binary
