73770 octal to binary

Here we will show you how to convert the octal number 73770 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 73770 from octal to binary are explained below.

Step 1)
Multiply the last digit in 73770 by 8⁰, multiply the second to last digit in 73770 by 8¹, multiply the third to last digit in 73770 by 8², multiply the fourth to last digit in 73770 by 8³, and so on, until all the digits are used:

0 × 8⁰ = 0
7 × 8¹ = 56
7 × 8² = 448
3 × 8³ = 1536
7 × 8⁴ = 28672

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

0 + 56 + 448 + 1536 + 28672 = 30712

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.

30712 ÷ 2 = 15356 with 0 remainder
15356 ÷ 2 = 7678 with 0 remainder
7678 ÷ 2 = 3839 with 0 remainder
3839 ÷ 2 = 1919 with 1 remainder
1919 ÷ 2 = 959 with 1 remainder
959 ÷ 2 = 479 with 1 remainder
479 ÷ 2 = 239 with 1 remainder
239 ÷ 2 = 119 with 1 remainder
119 ÷ 2 = 59 with 1 remainder
59 ÷ 2 = 29 with 1 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 73770 octal to binary:

73770 octal = 111011111111000 binary
