65642 octal to binary

Here we will show you how to convert the octal number 65642 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 65642 from octal to binary are explained below.

Step 1)
Multiply the last digit in 65642 by 8⁰, multiply the second to last digit in 65642 by 8¹, multiply the third to last digit in 65642 by 8², multiply the fourth to last digit in 65642 by 8³, and so on, until all the digits are used:

2 × 8⁰ = 2
4 × 8¹ = 32
6 × 8² = 384
5 × 8³ = 2560
6 × 8⁴ = 24576

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

2 + 32 + 384 + 2560 + 24576 = 27554

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.

27554 ÷ 2 = 13777 with 0 remainder
13777 ÷ 2 = 6888 with 1 remainder
6888 ÷ 2 = 3444 with 0 remainder
3444 ÷ 2 = 1722 with 0 remainder
1722 ÷ 2 = 861 with 0 remainder
861 ÷ 2 = 430 with 1 remainder
430 ÷ 2 = 215 with 0 remainder
215 ÷ 2 = 107 with 1 remainder
107 ÷ 2 = 53 with 1 remainder
53 ÷ 2 = 26 with 1 remainder
26 ÷ 2 = 13 with 0 remainder
13 ÷ 2 = 6 with 1 remainder
6 ÷ 2 = 3 with 0 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 65642 octal to binary:

65642 octal = 110101110100010 binary
