20604 octal to binary

Here we will show you how to convert the octal number 20604 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 20604 from octal to binary are explained below.

Step 1)
Multiply the last digit in 20604 by 8⁰, multiply the second to last digit in 20604 by 8¹, multiply the third to last digit in 20604 by 8², multiply the fourth to last digit in 20604 by 8³, and so on, until all the digits are used:

4 × 8⁰ = 4
0 × 8¹ = 0
6 × 8² = 384
0 × 8³ = 0
2 × 8⁴ = 8192

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

4 + 0 + 384 + 0 + 8192 = 8580

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.

8580 ÷ 2 = 4290 with 0 remainder
4290 ÷ 2 = 2145 with 0 remainder
2145 ÷ 2 = 1072 with 1 remainder
1072 ÷ 2 = 536 with 0 remainder
536 ÷ 2 = 268 with 0 remainder
268 ÷ 2 = 134 with 0 remainder
134 ÷ 2 = 67 with 0 remainder
67 ÷ 2 = 33 with 1 remainder
33 ÷ 2 = 16 with 1 remainder
16 ÷ 2 = 8 with 0 remainder
8 ÷ 2 = 4 with 0 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 20604 octal to binary:

20604 octal = 10000110000100 binary
