75731 octal to binary

Here we will show you how to convert the octal number 75731 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 75731 from octal to binary are explained below.

Step 1)
Multiply the last digit in 75731 by 8⁰, multiply the second to last digit in 75731 by 8¹, multiply the third to last digit in 75731 by 8², multiply the fourth to last digit in 75731 by 8³, and so on, until all the digits are used:

1 × 8⁰ = 1
3 × 8¹ = 24
7 × 8² = 448
5 × 8³ = 2560
7 × 8⁴ = 28672

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

1 + 24 + 448 + 2560 + 28672 = 31705

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.

31705 ÷ 2 = 15852 with 1 remainder
15852 ÷ 2 = 7926 with 0 remainder
7926 ÷ 2 = 3963 with 0 remainder
3963 ÷ 2 = 1981 with 1 remainder
1981 ÷ 2 = 990 with 1 remainder
990 ÷ 2 = 495 with 0 remainder
495 ÷ 2 = 247 with 1 remainder
247 ÷ 2 = 123 with 1 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 75731 octal to binary:

75731 octal = 111101111011001 binary
