A678 hexadecimal to binary

Here we will show you how to convert the hexadecimal number A678 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 A678 from hexadecimal to binary are explained below.

Step 1)
Multiply the last digit in A678 by 16⁰, multiply the second to last digit in A678 by 16¹, multiply the third to last digit in A678 by 16², multiply the fourth to last digit in A678 by 16³, and so on, until all the digits are used.

8 × 16⁰ = 8
7 × 16¹ = 112
6 × 16² = 1536
A × 16³ = 40960

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:

8 + 112 + 1536 + 40960 = 42616

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.

42616 ÷ 2 = 21308 with 0 remainder
21308 ÷ 2 = 10654 with 0 remainder
10654 ÷ 2 = 5327 with 0 remainder
5327 ÷ 2 = 2663 with 1 remainder
2663 ÷ 2 = 1331 with 1 remainder
1331 ÷ 2 = 665 with 1 remainder
665 ÷ 2 = 332 with 1 remainder
332 ÷ 2 = 166 with 0 remainder
166 ÷ 2 = 83 with 0 remainder
83 ÷ 2 = 41 with 1 remainder
41 ÷ 2 = 20 with 1 remainder
20 ÷ 2 = 10 with 0 remainder
10 ÷ 2 = 5 with 0 remainder
5 ÷ 2 = 2 with 1 remainder
2 ÷ 2 = 1 with 0 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 A678 hexadecimal to binary:

A678 hexadecimal = 1010011001111000 binary
