7272 octal to binary

Here we will show you how to convert the octal number 7272 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 7272 from octal to binary are explained below.

Step 1)
Multiply the last digit in 7272 by 8⁰, multiply the second to last digit in 7272 by 8¹, multiply the third to last digit in 7272 by 8², multiply the fourth to last digit in 7272 by 8³, and so on, until all the digits are used:

2 × 8⁰ = 2
7 × 8¹ = 56
2 × 8² = 128
7 × 8³ = 3584

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

2 + 56 + 128 + 3584 = 3770

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.

3770 ÷ 2 = 1885 with 0 remainder
1885 ÷ 2 = 942 with 1 remainder
942 ÷ 2 = 471 with 0 remainder
471 ÷ 2 = 235 with 1 remainder
235 ÷ 2 = 117 with 1 remainder
117 ÷ 2 = 58 with 1 remainder
58 ÷ 2 = 29 with 0 remainder
29 ÷ 2 = 14 with 1 remainder
14 ÷ 2 = 7 with 0 remainder
7 ÷ 2 = 3 with 1 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 7272 octal to binary:

7272 octal = 111010111010 binary
