30407 octal to binary

Here we will show you how to convert the octal number 30407 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 30407 from octal to binary are explained below.

Step 1)
Multiply the last digit in 30407 by 8⁰, multiply the second to last digit in 30407 by 8¹, multiply the third to last digit in 30407 by 8², multiply the fourth to last digit in 30407 by 8³, and so on, until all the digits are used:

7 × 8⁰ = 7
0 × 8¹ = 0
4 × 8² = 256
0 × 8³ = 0
3 × 8⁴ = 12288

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

7 + 0 + 256 + 0 + 12288 = 12551

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.

12551 ÷ 2 = 6275 with 1 remainder
6275 ÷ 2 = 3137 with 1 remainder
3137 ÷ 2 = 1568 with 1 remainder
1568 ÷ 2 = 784 with 0 remainder
784 ÷ 2 = 392 with 0 remainder
392 ÷ 2 = 196 with 0 remainder
196 ÷ 2 = 98 with 0 remainder
98 ÷ 2 = 49 with 0 remainder
49 ÷ 2 = 24 with 1 remainder
24 ÷ 2 = 12 with 0 remainder
12 ÷ 2 = 6 with 0 remainder
6 ÷ 2 = 3 with 0 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 30407 octal to binary:

30407 octal = 11000100000111 binary
