45771 octal to binary

Here we will show you how to convert the octal number 45771 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 45771 from octal to binary are explained below.

Step 1)
Multiply the last digit in 45771 by 8⁰, multiply the second to last digit in 45771 by 8¹, multiply the third to last digit in 45771 by 8², multiply the fourth to last digit in 45771 by 8³, and so on, until all the digits are used:

1 × 8⁰ = 1
7 × 8¹ = 56
7 × 8² = 448
5 × 8³ = 2560
4 × 8⁴ = 16384

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

1 + 56 + 448 + 2560 + 16384 = 19449

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.

19449 ÷ 2 = 9724 with 1 remainder
9724 ÷ 2 = 4862 with 0 remainder
4862 ÷ 2 = 2431 with 0 remainder
2431 ÷ 2 = 1215 with 1 remainder
1215 ÷ 2 = 607 with 1 remainder
607 ÷ 2 = 303 with 1 remainder
303 ÷ 2 = 151 with 1 remainder
151 ÷ 2 = 75 with 1 remainder
75 ÷ 2 = 37 with 1 remainder
37 ÷ 2 = 18 with 1 remainder
18 ÷ 2 = 9 with 0 remainder
9 ÷ 2 = 4 with 1 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 45771 octal to binary:

45771 octal = 100101111111001 binary
