57640 octal to binary

Here we will show you how to convert the octal number 57640 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 57640 from octal to binary are explained below.

Step 1)
Multiply the last digit in 57640 by 8⁰, multiply the second to last digit in 57640 by 8¹, multiply the third to last digit in 57640 by 8², multiply the fourth to last digit in 57640 by 8³, and so on, until all the digits are used:

0 × 8⁰ = 0
4 × 8¹ = 32
6 × 8² = 384
7 × 8³ = 3584
5 × 8⁴ = 20480

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

0 + 32 + 384 + 3584 + 20480 = 24480

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.

24480 ÷ 2 = 12240 with 0 remainder
12240 ÷ 2 = 6120 with 0 remainder
6120 ÷ 2 = 3060 with 0 remainder
3060 ÷ 2 = 1530 with 0 remainder
1530 ÷ 2 = 765 with 0 remainder
765 ÷ 2 = 382 with 1 remainder
382 ÷ 2 = 191 with 0 remainder
191 ÷ 2 = 95 with 1 remainder
95 ÷ 2 = 47 with 1 remainder
47 ÷ 2 = 23 with 1 remainder
23 ÷ 2 = 11 with 1 remainder
11 ÷ 2 = 5 with 1 remainder
5 ÷ 2 = 2 with 1 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 57640 octal to binary:

57640 octal = 101111110100000 binary
