74513 octal to binary

Here we will show you how to convert the octal number 74513 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 74513 from octal to binary are explained below.

Step 1)
Multiply the last digit in 74513 by 8⁰, multiply the second to last digit in 74513 by 8¹, multiply the third to last digit in 74513 by 8², multiply the fourth to last digit in 74513 by 8³, and so on, until all the digits are used:

3 × 8⁰ = 3
1 × 8¹ = 8
5 × 8² = 320
4 × 8³ = 2048
7 × 8⁴ = 28672

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

3 + 8 + 320 + 2048 + 28672 = 31051

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.

31051 ÷ 2 = 15525 with 1 remainder
15525 ÷ 2 = 7762 with 1 remainder
7762 ÷ 2 = 3881 with 0 remainder
3881 ÷ 2 = 1940 with 1 remainder
1940 ÷ 2 = 970 with 0 remainder
970 ÷ 2 = 485 with 0 remainder
485 ÷ 2 = 242 with 1 remainder
242 ÷ 2 = 121 with 0 remainder
121 ÷ 2 = 60 with 1 remainder
60 ÷ 2 = 30 with 0 remainder
30 ÷ 2 = 15 with 0 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 74513 octal to binary:

74513 octal = 111100101001011 binary
