72A5 hexadecimal to binary

Here we will show you how to convert the hexadecimal number 72A5 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 72A5 from hexadecimal to binary are explained below.

Step 1)
Multiply the last digit in 72A5 by 16⁰, multiply the second to last digit in 72A5 by 16¹, multiply the third to last digit in 72A5 by 16², multiply the fourth to last digit in 72A5 by 16³, and so on, until all the digits are used.

5 × 16⁰ = 5
A × 16¹ = 160
2 × 16² = 512
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:

5 + 160 + 512 + 28672 = 29349

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.

29349 ÷ 2 = 14674 with 1 remainder
14674 ÷ 2 = 7337 with 0 remainder
7337 ÷ 2 = 3668 with 1 remainder
3668 ÷ 2 = 1834 with 0 remainder
1834 ÷ 2 = 917 with 0 remainder
917 ÷ 2 = 458 with 1 remainder
458 ÷ 2 = 229 with 0 remainder
229 ÷ 2 = 114 with 1 remainder
114 ÷ 2 = 57 with 0 remainder
57 ÷ 2 = 28 with 1 remainder
28 ÷ 2 = 14 with 0 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 72A5 hexadecimal to binary:

72A5 hexadecimal = 111001010100101 binary
