74A9 hexadecimal to binary

Here we will show you how to convert the hexadecimal number 74A9 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 74A9 from hexadecimal to binary are explained below.

Step 1)
Multiply the last digit in 74A9 by 16⁰, multiply the second to last digit in 74A9 by 16¹, multiply the third to last digit in 74A9 by 16², multiply the fourth to last digit in 74A9 by 16³, and so on, until all the digits are used.

9 × 16⁰ = 9
A × 16¹ = 160
4 × 16² = 1024
7 × 16³ = 28672

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:

9 + 160 + 1024 + 28672 = 29865

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.

29865 ÷ 2 = 14932 with 1 remainder
14932 ÷ 2 = 7466 with 0 remainder
7466 ÷ 2 = 3733 with 0 remainder
3733 ÷ 2 = 1866 with 1 remainder
1866 ÷ 2 = 933 with 0 remainder
933 ÷ 2 = 466 with 1 remainder
466 ÷ 2 = 233 with 0 remainder
233 ÷ 2 = 116 with 1 remainder
116 ÷ 2 = 58 with 0 remainder
58 ÷ 2 = 29 with 0 remainder
29 ÷ 2 = 14 with 1 remainder
14 ÷ 2 = 7 with 0 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 74A9 hexadecimal to binary:

74A9 hexadecimal = 111010010101001 binary
