42146 octal to binary

Here we will show you how to convert the octal number 42146 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 42146 from octal to binary are explained below.

Step 1)
Multiply the last digit in 42146 by 8⁰, multiply the second to last digit in 42146 by 8¹, multiply the third to last digit in 42146 by 8², multiply the fourth to last digit in 42146 by 8³, and so on, until all the digits are used:

6 × 8⁰ = 6
4 × 8¹ = 32
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:

6 + 32 + 64 + 1024 + 16384 = 17510

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.

17510 ÷ 2 = 8755 with 0 remainder
8755 ÷ 2 = 4377 with 1 remainder
4377 ÷ 2 = 2188 with 1 remainder
2188 ÷ 2 = 1094 with 0 remainder
1094 ÷ 2 = 547 with 0 remainder
547 ÷ 2 = 273 with 1 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 42146 octal to binary:

42146 octal = 100010001100110 binary
