65720 octal to binary

Here we will show you how to convert the octal number 65720 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 65720 from octal to binary are explained below.

Step 1)
Multiply the last digit in 65720 by 8⁰, multiply the second to last digit in 65720 by 8¹, multiply the third to last digit in 65720 by 8², multiply the fourth to last digit in 65720 by 8³, and so on, until all the digits are used:

0 × 8⁰ = 0
2 × 8¹ = 16
7 × 8² = 448
5 × 8³ = 2560
6 × 8⁴ = 24576

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

0 + 16 + 448 + 2560 + 24576 = 27600

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.

27600 ÷ 2 = 13800 with 0 remainder
13800 ÷ 2 = 6900 with 0 remainder
6900 ÷ 2 = 3450 with 0 remainder
3450 ÷ 2 = 1725 with 0 remainder
1725 ÷ 2 = 862 with 1 remainder
862 ÷ 2 = 431 with 0 remainder
431 ÷ 2 = 215 with 1 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 65720 octal to binary:

65720 octal = 110101111010000 binary
