10400 octal to binary

Here we will show you how to convert the octal number 10400 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 10400 from octal to binary are explained below.

Step 1)
Multiply the last digit in 10400 by 8⁰, multiply the second to last digit in 10400 by 8¹, multiply the third to last digit in 10400 by 8², multiply the fourth to last digit in 10400 by 8³, and so on, until all the digits are used:

0 × 8⁰ = 0
0 × 8¹ = 0
4 × 8² = 256
0 × 8³ = 0
1 × 8⁴ = 4096

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

0 + 0 + 256 + 0 + 4096 = 4352

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.

4352 ÷ 2 = 2176 with 0 remainder
2176 ÷ 2 = 1088 with 0 remainder
1088 ÷ 2 = 544 with 0 remainder
544 ÷ 2 = 272 with 0 remainder
272 ÷ 2 = 136 with 0 remainder
136 ÷ 2 = 68 with 0 remainder
68 ÷ 2 = 34 with 0 remainder
34 ÷ 2 = 17 with 0 remainder
17 ÷ 2 = 8 with 1 remainder
8 ÷ 2 = 4 with 0 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 10400 octal to binary:

10400 octal = 1000100000000 binary
