Here we will show you how to convert the octal number 74551 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 74551 from octal to binary are explained below.
Step 1)
Multiply the last digit in 74551 by 8⁰, multiply the second to last digit in 74551 by 8¹, multiply the third to last digit in 74551 by 8², multiply the fourth to last digit in 74551 by 8³, and so on, until all the digits are used:
1 × 8⁰ = 1
5 × 8¹ = 40
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:
1 + 40 + 320 + 2048 + 28672 = 31081
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.
31081 ÷ 2 = 15540 with 1 remainder
15540 ÷ 2 = 7770 with 0 remainder
7770 ÷ 2 = 3885 with 0 remainder
3885 ÷ 2 = 1942 with 1 remainder
1942 ÷ 2 = 971 with 0 remainder
971 ÷ 2 = 485 with 1 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 74551 octal to binary:
74551 octal = 111100101101001 binary
