40731 octal to binary

Here we will show you how to convert the octal number 40731 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 40731 from octal to binary are explained below.

Step 1)
Multiply the last digit in 40731 by 8⁰, multiply the second to last digit in 40731 by 8¹, multiply the third to last digit in 40731 by 8², multiply the fourth to last digit in 40731 by 8³, and so on, until all the digits are used:

1 × 8⁰ = 1
3 × 8¹ = 24
7 × 8² = 448
0 × 8³ = 0
4 × 8⁴ = 16384

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

1 + 24 + 448 + 0 + 16384 = 16857

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.

16857 ÷ 2 = 8428 with 1 remainder
8428 ÷ 2 = 4214 with 0 remainder
4214 ÷ 2 = 2107 with 0 remainder
2107 ÷ 2 = 1053 with 1 remainder
1053 ÷ 2 = 526 with 1 remainder
526 ÷ 2 = 263 with 0 remainder
263 ÷ 2 = 131 with 1 remainder
131 ÷ 2 = 65 with 1 remainder
65 ÷ 2 = 32 with 1 remainder
32 ÷ 2 = 16 with 0 remainder
16 ÷ 2 = 8 with 0 remainder
8 ÷ 2 = 4 with 0 remainder
4 ÷ 2 = 2 with 0 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 40731 octal to binary:

40731 octal = 100000111011001 binary
