15661 octal to binary

Here we will show you how to convert the octal number 15661 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 15661 from octal to binary are explained below.

Step 1)
Multiply the last digit in 15661 by 8⁰, multiply the second to last digit in 15661 by 8¹, multiply the third to last digit in 15661 by 8², multiply the fourth to last digit in 15661 by 8³, and so on, until all the digits are used:

1 × 8⁰ = 1
6 × 8¹ = 48
6 × 8² = 384
5 × 8³ = 2560
1 × 8⁴ = 4096

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

1 + 48 + 384 + 2560 + 4096 = 7089

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.

7089 ÷ 2 = 3544 with 1 remainder
3544 ÷ 2 = 1772 with 0 remainder
1772 ÷ 2 = 886 with 0 remainder
886 ÷ 2 = 443 with 0 remainder
443 ÷ 2 = 221 with 1 remainder
221 ÷ 2 = 110 with 1 remainder
110 ÷ 2 = 55 with 0 remainder
55 ÷ 2 = 27 with 1 remainder
27 ÷ 2 = 13 with 1 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 15661 octal to binary:

15661 octal = 1101110110001 binary
