3C91 hexadecimal to binary

Here we will show you how to convert the hexadecimal number 3C91 to a binary number. First note that the hexadecimal number system has sixteen different digits (0 1 2 3 4 5 6 7 8 9 A B C D E F) and the binary number system has only two different digits (0 and 1).

The four steps used to convert 3C91 from hexadecimal to binary are explained below.

Step 1)
Multiply the last digit in 3C91 by 16⁰, multiply the second to last digit in 3C91 by 16¹, multiply the third to last digit in 3C91 by 16², multiply the fourth to last digit in 3C91 by 16³, and so on, until all the digits are used.

1 × 16⁰ = 1
9 × 16¹ = 144
C × 16² = 3072
3 × 16³ = 12288

Remember that the hexadecimal number system has sixteen different digits, so when doing the above calculation, we use the following values if applicable: A=10, B=11, C=12, D=13, E=14, and F=15.

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

1 + 144 + 3072 + 12288 = 15505

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.

15505 ÷ 2 = 7752 with 1 remainder
7752 ÷ 2 = 3876 with 0 remainder
3876 ÷ 2 = 1938 with 0 remainder
1938 ÷ 2 = 969 with 0 remainder
969 ÷ 2 = 484 with 1 remainder
484 ÷ 2 = 242 with 0 remainder
242 ÷ 2 = 121 with 0 remainder
121 ÷ 2 = 60 with 1 remainder
60 ÷ 2 = 30 with 0 remainder
30 ÷ 2 = 15 with 0 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 3C91 hexadecimal to binary:

3C91 hexadecimal = 11110010010001 binary
