D257 hexadecimal to binary

Here we will show you how to convert the hexadecimal number D257 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 D257 from hexadecimal to binary are explained below.

Step 1)
Multiply the last digit in D257 by 16⁰, multiply the second to last digit in D257 by 16¹, multiply the third to last digit in D257 by 16², multiply the fourth to last digit in D257 by 16³, and so on, until all the digits are used.

7 × 16⁰ = 7
5 × 16¹ = 80
2 × 16² = 512
D × 16³ = 53248

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:

7 + 80 + 512 + 53248 = 53847

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.

53847 ÷ 2 = 26923 with 1 remainder
26923 ÷ 2 = 13461 with 1 remainder
13461 ÷ 2 = 6730 with 1 remainder
6730 ÷ 2 = 3365 with 0 remainder
3365 ÷ 2 = 1682 with 1 remainder
1682 ÷ 2 = 841 with 0 remainder
841 ÷ 2 = 420 with 1 remainder
420 ÷ 2 = 210 with 0 remainder
210 ÷ 2 = 105 with 0 remainder
105 ÷ 2 = 52 with 1 remainder
52 ÷ 2 = 26 with 0 remainder
26 ÷ 2 = 13 with 0 remainder
13 ÷ 2 = 6 with 1 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 D257 hexadecimal to binary:

D257 hexadecimal = 1101001001010111 binary
