75561 octal to binary

Here we will show you how to convert the octal number 75561 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 75561 from octal to binary are explained below.

Step 1)
Multiply the last digit in 75561 by 8⁰, multiply the second to last digit in 75561 by 8¹, multiply the third to last digit in 75561 by 8², multiply the fourth to last digit in 75561 by 8³, and so on, until all the digits are used:

1 × 8⁰ = 1
6 × 8¹ = 48
5 × 8² = 320
5 × 8³ = 2560
7 × 8⁴ = 28672

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

1 + 48 + 320 + 2560 + 28672 = 31601

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.

31601 ÷ 2 = 15800 with 1 remainder
15800 ÷ 2 = 7900 with 0 remainder
7900 ÷ 2 = 3950 with 0 remainder
3950 ÷ 2 = 1975 with 0 remainder
1975 ÷ 2 = 987 with 1 remainder
987 ÷ 2 = 493 with 1 remainder
493 ÷ 2 = 246 with 1 remainder
246 ÷ 2 = 123 with 0 remainder
123 ÷ 2 = 61 with 1 remainder
61 ÷ 2 = 30 with 1 remainder
30 ÷ 2 = 15 with 0 remainder
15 ÷ 2 = 7 with 1 remainder
7 ÷ 2 = 3 with 1 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 75561 octal to binary:

75561 octal = 111101101110001 binary
