77244 octal to binary

Here we will show you how to convert the octal number 77244 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 77244 from octal to binary are explained below.

Step 1)
Multiply the last digit in 77244 by 8⁰, multiply the second to last digit in 77244 by 8¹, multiply the third to last digit in 77244 by 8², multiply the fourth to last digit in 77244 by 8³, and so on, until all the digits are used:

4 × 8⁰ = 4
4 × 8¹ = 32
2 × 8² = 128
7 × 8³ = 3584
7 × 8⁴ = 28672

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

4 + 32 + 128 + 3584 + 28672 = 32420

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.

32420 ÷ 2 = 16210 with 0 remainder
16210 ÷ 2 = 8105 with 0 remainder
8105 ÷ 2 = 4052 with 1 remainder
4052 ÷ 2 = 2026 with 0 remainder
2026 ÷ 2 = 1013 with 0 remainder
1013 ÷ 2 = 506 with 1 remainder
506 ÷ 2 = 253 with 0 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 77244 octal to binary:

77244 octal = 111111010100100 binary
