77164 octal to binary

Here we will show you how to convert the octal number 77164 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 77164 from octal to binary are explained below.

Step 1)
Multiply the last digit in 77164 by 8⁰, multiply the second to last digit in 77164 by 8¹, multiply the third to last digit in 77164 by 8², multiply the fourth to last digit in 77164 by 8³, and so on, until all the digits are used:

4 × 8⁰ = 4
6 × 8¹ = 48
1 × 8² = 64
7 × 8³ = 3584
7 × 8⁴ = 28672

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

4 + 48 + 64 + 3584 + 28672 = 32372

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.

32372 ÷ 2 = 16186 with 0 remainder
16186 ÷ 2 = 8093 with 0 remainder
8093 ÷ 2 = 4046 with 1 remainder
4046 ÷ 2 = 2023 with 0 remainder
2023 ÷ 2 = 1011 with 1 remainder
1011 ÷ 2 = 505 with 1 remainder
505 ÷ 2 = 252 with 1 remainder
252 ÷ 2 = 126 with 0 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 77164 octal to binary:

77164 octal = 111111001110100 binary
