15240 octal to binary

Here we will show you how to convert the octal number 15240 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 15240 from octal to binary are explained below.

Step 1)
Multiply the last digit in 15240 by 8⁰, multiply the second to last digit in 15240 by 8¹, multiply the third to last digit in 15240 by 8², multiply the fourth to last digit in 15240 by 8³, and so on, until all the digits are used:

0 × 8⁰ = 0
4 × 8¹ = 32
2 × 8² = 128
5 × 8³ = 2560
1 × 8⁴ = 4096

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

0 + 32 + 128 + 2560 + 4096 = 6816

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.

6816 ÷ 2 = 3408 with 0 remainder
3408 ÷ 2 = 1704 with 0 remainder
1704 ÷ 2 = 852 with 0 remainder
852 ÷ 2 = 426 with 0 remainder
426 ÷ 2 = 213 with 0 remainder
213 ÷ 2 = 106 with 1 remainder
106 ÷ 2 = 53 with 0 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 15240 octal to binary:

15240 octal = 1101010100000 binary
