10642 octal to binary

Here we will show you how to convert the octal number 10642 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 10642 from octal to binary are explained below.

Step 1)
Multiply the last digit in 10642 by 8⁰, multiply the second to last digit in 10642 by 8¹, multiply the third to last digit in 10642 by 8², multiply the fourth to last digit in 10642 by 8³, and so on, until all the digits are used:

2 × 8⁰ = 2
4 × 8¹ = 32
6 × 8² = 384
0 × 8³ = 0
1 × 8⁴ = 4096

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

2 + 32 + 384 + 0 + 4096 = 4514

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.

4514 ÷ 2 = 2257 with 0 remainder
2257 ÷ 2 = 1128 with 1 remainder
1128 ÷ 2 = 564 with 0 remainder
564 ÷ 2 = 282 with 0 remainder
282 ÷ 2 = 141 with 0 remainder
141 ÷ 2 = 70 with 1 remainder
70 ÷ 2 = 35 with 0 remainder
35 ÷ 2 = 17 with 1 remainder
17 ÷ 2 = 8 with 1 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 10642 octal to binary:

10642 octal = 1000110100010 binary
