77771 octal to binary

Here we will show you how to convert the octal number 77771 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 77771 from octal to binary are explained below.

Step 1)
Multiply the last digit in 77771 by 8⁰, multiply the second to last digit in 77771 by 8¹, multiply the third to last digit in 77771 by 8², multiply the fourth to last digit in 77771 by 8³, and so on, until all the digits are used:

1 × 8⁰ = 1
7 × 8¹ = 56
7 × 8² = 448
7 × 8³ = 3584
7 × 8⁴ = 28672

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

1 + 56 + 448 + 3584 + 28672 = 32761

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.

32761 ÷ 2 = 16380 with 1 remainder
16380 ÷ 2 = 8190 with 0 remainder
8190 ÷ 2 = 4095 with 0 remainder
4095 ÷ 2 = 2047 with 1 remainder
2047 ÷ 2 = 1023 with 1 remainder
1023 ÷ 2 = 511 with 1 remainder
511 ÷ 2 = 255 with 1 remainder
255 ÷ 2 = 127 with 1 remainder
127 ÷ 2 = 63 with 1 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 77771 octal to binary:

77771 octal = 111111111111001 binary
