7646 octal to binary

Here we will show you how to convert the octal number 7646 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 7646 from octal to binary are explained below.

Step 1)
Multiply the last digit in 7646 by 8⁰, multiply the second to last digit in 7646 by 8¹, multiply the third to last digit in 7646 by 8², multiply the fourth to last digit in 7646 by 8³, and so on, until all the digits are used:

6 × 8⁰ = 6
4 × 8¹ = 32
6 × 8² = 384
7 × 8³ = 3584

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

6 + 32 + 384 + 3584 = 4006

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.

4006 ÷ 2 = 2003 with 0 remainder
2003 ÷ 2 = 1001 with 1 remainder
1001 ÷ 2 = 500 with 1 remainder
500 ÷ 2 = 250 with 0 remainder
250 ÷ 2 = 125 with 0 remainder
125 ÷ 2 = 62 with 1 remainder
62 ÷ 2 = 31 with 0 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 7646 octal to binary:

7646 octal = 111110100110 binary
