15203 octal to binary

Here we will show you how to convert the octal number 15203 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 15203 from octal to binary are explained below.

Step 1)
Multiply the last digit in 15203 by 8⁰, multiply the second to last digit in 15203 by 8¹, multiply the third to last digit in 15203 by 8², multiply the fourth to last digit in 15203 by 8³, and so on, until all the digits are used:

3 × 8⁰ = 3
0 × 8¹ = 0
2 × 8² = 128
5 × 8³ = 2560
1 × 8⁴ = 4096

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

3 + 0 + 128 + 2560 + 4096 = 6787

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.

6787 ÷ 2 = 3393 with 1 remainder
3393 ÷ 2 = 1696 with 1 remainder
1696 ÷ 2 = 848 with 0 remainder
848 ÷ 2 = 424 with 0 remainder
424 ÷ 2 = 212 with 0 remainder
212 ÷ 2 = 106 with 0 remainder
106 ÷ 2 = 53 with 0 remainder
53 ÷ 2 = 26 with 1 remainder
26 ÷ 2 = 13 with 0 remainder
13 ÷ 2 = 6 with 1 remainder
6 ÷ 2 = 3 with 0 remainder
3 ÷ 2 = 1 with 1 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 15203 octal to binary:

15203 octal = 1101010000011 binary
