13531 octal to binary

Here we will show you how to convert the octal number 13531 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 13531 from octal to binary are explained below.

Step 1)
Multiply the last digit in 13531 by 8⁰, multiply the second to last digit in 13531 by 8¹, multiply the third to last digit in 13531 by 8², multiply the fourth to last digit in 13531 by 8³, and so on, until all the digits are used:

1 × 8⁰ = 1
3 × 8¹ = 24
5 × 8² = 320
3 × 8³ = 1536
1 × 8⁴ = 4096

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

1 + 24 + 320 + 1536 + 4096 = 5977

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.

5977 ÷ 2 = 2988 with 1 remainder
2988 ÷ 2 = 1494 with 0 remainder
1494 ÷ 2 = 747 with 0 remainder
747 ÷ 2 = 373 with 1 remainder
373 ÷ 2 = 186 with 1 remainder
186 ÷ 2 = 93 with 0 remainder
93 ÷ 2 = 46 with 1 remainder
46 ÷ 2 = 23 with 0 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 13531 octal to binary:

13531 octal = 1011101011001 binary
