4312 octal to binary

Here we will show you how to convert the octal number 4312 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 4312 from octal to binary are explained below.

Step 1)
Multiply the last digit in 4312 by 8⁰, multiply the second to last digit in 4312 by 8¹, multiply the third to last digit in 4312 by 8², multiply the fourth to last digit in 4312 by 8³, and so on, until all the digits are used:

2 × 8⁰ = 2
1 × 8¹ = 8
3 × 8² = 192
4 × 8³ = 2048

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

2 + 8 + 192 + 2048 = 2250

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.

2250 ÷ 2 = 1125 with 0 remainder
1125 ÷ 2 = 562 with 1 remainder
562 ÷ 2 = 281 with 0 remainder
281 ÷ 2 = 140 with 1 remainder
140 ÷ 2 = 70 with 0 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 4312 octal to binary:

4312 octal = 100011001010 binary
