668D hexadecimal to binary

Here we will show you how to convert the hexadecimal number 668D 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 668D from hexadecimal to binary are explained below.

Step 1)
Multiply the last digit in 668D by 16⁰, multiply the second to last digit in 668D by 16¹, multiply the third to last digit in 668D by 16², multiply the fourth to last digit in 668D by 16³, and so on, until all the digits are used.

D × 16⁰ = 13
8 × 16¹ = 128
6 × 16² = 1536
6 × 16³ = 24576

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:

13 + 128 + 1536 + 24576 = 26253

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.

26253 ÷ 2 = 13126 with 1 remainder
13126 ÷ 2 = 6563 with 0 remainder
6563 ÷ 2 = 3281 with 1 remainder
3281 ÷ 2 = 1640 with 1 remainder
1640 ÷ 2 = 820 with 0 remainder
820 ÷ 2 = 410 with 0 remainder
410 ÷ 2 = 205 with 0 remainder
205 ÷ 2 = 102 with 1 remainder
102 ÷ 2 = 51 with 0 remainder
51 ÷ 2 = 25 with 1 remainder
25 ÷ 2 = 12 with 1 remainder
12 ÷ 2 = 6 with 0 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 668D hexadecimal to binary:

668D hexadecimal = 110011010001101 binary
