74745 octal to binary

Here we will show you how to convert the octal number 74745 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 74745 from octal to binary are explained below.

Step 1)
Multiply the last digit in 74745 by 8⁰, multiply the second to last digit in 74745 by 8¹, multiply the third to last digit in 74745 by 8², multiply the fourth to last digit in 74745 by 8³, and so on, until all the digits are used:

5 × 8⁰ = 5
4 × 8¹ = 32
7 × 8² = 448
4 × 8³ = 2048
7 × 8⁴ = 28672

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

5 + 32 + 448 + 2048 + 28672 = 31205

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.

31205 ÷ 2 = 15602 with 1 remainder
15602 ÷ 2 = 7801 with 0 remainder
7801 ÷ 2 = 3900 with 1 remainder
3900 ÷ 2 = 1950 with 0 remainder
1950 ÷ 2 = 975 with 0 remainder
975 ÷ 2 = 487 with 1 remainder
487 ÷ 2 = 243 with 1 remainder
243 ÷ 2 = 121 with 1 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 74745 octal to binary:

74745 octal = 111100111100101 binary
