74427 octal to binary

Here we will show you how to convert the octal number 74427 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 74427 from octal to binary are explained below.

Step 1)
Multiply the last digit in 74427 by 8⁰, multiply the second to last digit in 74427 by 8¹, multiply the third to last digit in 74427 by 8², multiply the fourth to last digit in 74427 by 8³, and so on, until all the digits are used:

7 × 8⁰ = 7
2 × 8¹ = 16
4 × 8² = 256
4 × 8³ = 2048
7 × 8⁴ = 28672

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

7 + 16 + 256 + 2048 + 28672 = 30999

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.

30999 ÷ 2 = 15499 with 1 remainder
15499 ÷ 2 = 7749 with 1 remainder
7749 ÷ 2 = 3874 with 1 remainder
3874 ÷ 2 = 1937 with 0 remainder
1937 ÷ 2 = 968 with 1 remainder
968 ÷ 2 = 484 with 0 remainder
484 ÷ 2 = 242 with 0 remainder
242 ÷ 2 = 121 with 0 remainder
121 ÷ 2 = 60 with 1 remainder
60 ÷ 2 = 30 with 0 remainder
30 ÷ 2 = 15 with 0 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 74427 octal to binary:

74427 octal = 111100100010111 binary
