77501 octal to binary

Here we will show you how to convert the octal number 77501 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 77501 from octal to binary are explained below.

Step 1)
Multiply the last digit in 77501 by 8⁰, multiply the second to last digit in 77501 by 8¹, multiply the third to last digit in 77501 by 8², multiply the fourth to last digit in 77501 by 8³, and so on, until all the digits are used:

1 × 8⁰ = 1
0 × 8¹ = 0
5 × 8² = 320
7 × 8³ = 3584
7 × 8⁴ = 28672

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

1 + 0 + 320 + 3584 + 28672 = 32577

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.

32577 ÷ 2 = 16288 with 1 remainder
16288 ÷ 2 = 8144 with 0 remainder
8144 ÷ 2 = 4072 with 0 remainder
4072 ÷ 2 = 2036 with 0 remainder
2036 ÷ 2 = 1018 with 0 remainder
1018 ÷ 2 = 509 with 0 remainder
509 ÷ 2 = 254 with 1 remainder
254 ÷ 2 = 127 with 0 remainder
127 ÷ 2 = 63 with 1 remainder
63 ÷ 2 = 31 with 1 remainder
31 ÷ 2 = 15 with 1 remainder
15 ÷ 2 = 7 with 1 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 77501 octal to binary:

77501 octal = 111111101000001 binary
