77317 octal to binary

Here we will show you how to convert the octal number 77317 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 77317 from octal to binary are explained below.

Step 1)
Multiply the last digit in 77317 by 8⁰, multiply the second to last digit in 77317 by 8¹, multiply the third to last digit in 77317 by 8², multiply the fourth to last digit in 77317 by 8³, and so on, until all the digits are used:

7 × 8⁰ = 7
1 × 8¹ = 8
3 × 8² = 192
7 × 8³ = 3584
7 × 8⁴ = 28672

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

7 + 8 + 192 + 3584 + 28672 = 32463

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.

32463 ÷ 2 = 16231 with 1 remainder
16231 ÷ 2 = 8115 with 1 remainder
8115 ÷ 2 = 4057 with 1 remainder
4057 ÷ 2 = 2028 with 1 remainder
2028 ÷ 2 = 1014 with 0 remainder
1014 ÷ 2 = 507 with 0 remainder
507 ÷ 2 = 253 with 1 remainder
253 ÷ 2 = 126 with 1 remainder
126 ÷ 2 = 63 with 0 remainder
63 ÷ 2 = 31 with 1 remainder
31 ÷ 2 = 15 with 1 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 77317 octal to binary:

77317 octal = 111111011001111 binary
