454 octal to binary

Here we will show you how to convert the octal number 454 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 454 from octal to binary are explained below.

Step 1)
Multiply the last digit in 454 by 8⁰, multiply the second to last digit in 454 by 8¹, multiply the third to last digit in 454 by 8², multiply the fourth to last digit in 454 by 8³, and so on, until all the digits are used:

4 × 8⁰ = 4
5 × 8¹ = 40
4 × 8² = 256

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

4 + 40 + 256 = 300

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.

300 ÷ 2 = 150 with 0 remainder
150 ÷ 2 = 75 with 0 remainder
75 ÷ 2 = 37 with 1 remainder
37 ÷ 2 = 18 with 1 remainder
18 ÷ 2 = 9 with 0 remainder
9 ÷ 2 = 4 with 1 remainder
4 ÷ 2 = 2 with 0 remainder
2 ÷ 2 = 1 with 0 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 454 octal to binary:

454 octal = 100101100 binary
