52421 octal to binary

Here we will show you how to convert the octal number 52421 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 52421 from octal to binary are explained below.

Step 1)
Multiply the last digit in 52421 by 8⁰, multiply the second to last digit in 52421 by 8¹, multiply the third to last digit in 52421 by 8², multiply the fourth to last digit in 52421 by 8³, and so on, until all the digits are used:

1 × 8⁰ = 1
2 × 8¹ = 16
4 × 8² = 256
2 × 8³ = 1024
5 × 8⁴ = 20480

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

1 + 16 + 256 + 1024 + 20480 = 21777

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.

21777 ÷ 2 = 10888 with 1 remainder
10888 ÷ 2 = 5444 with 0 remainder
5444 ÷ 2 = 2722 with 0 remainder
2722 ÷ 2 = 1361 with 0 remainder
1361 ÷ 2 = 680 with 1 remainder
680 ÷ 2 = 340 with 0 remainder
340 ÷ 2 = 170 with 0 remainder
170 ÷ 2 = 85 with 0 remainder
85 ÷ 2 = 42 with 1 remainder
42 ÷ 2 = 21 with 0 remainder
21 ÷ 2 = 10 with 1 remainder
10 ÷ 2 = 5 with 0 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 52421 octal to binary:

52421 octal = 101010100010001 binary
