42103 octal to binary

Here we will show you how to convert the octal number 42103 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 42103 from octal to binary are explained below.

Step 1)
Multiply the last digit in 42103 by 8⁰, multiply the second to last digit in 42103 by 8¹, multiply the third to last digit in 42103 by 8², multiply the fourth to last digit in 42103 by 8³, and so on, until all the digits are used:

3 × 8⁰ = 3
0 × 8¹ = 0
1 × 8² = 64
2 × 8³ = 1024
4 × 8⁴ = 16384

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

3 + 0 + 64 + 1024 + 16384 = 17475

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.

17475 ÷ 2 = 8737 with 1 remainder
8737 ÷ 2 = 4368 with 1 remainder
4368 ÷ 2 = 2184 with 0 remainder
2184 ÷ 2 = 1092 with 0 remainder
1092 ÷ 2 = 546 with 0 remainder
546 ÷ 2 = 273 with 0 remainder
273 ÷ 2 = 136 with 1 remainder
136 ÷ 2 = 68 with 0 remainder
68 ÷ 2 = 34 with 0 remainder
34 ÷ 2 = 17 with 0 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 42103 octal to binary:

42103 octal = 100010001000011 binary
