390A hexadecimal to binary

Here we will show you how to convert the hexadecimal number 390A 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 390A from hexadecimal to binary are explained below.

Step 1)
Multiply the last digit in 390A by 16⁰, multiply the second to last digit in 390A by 16¹, multiply the third to last digit in 390A by 16², multiply the fourth to last digit in 390A by 16³, and so on, until all the digits are used.

A × 16⁰ = 10
0 × 16¹ = 0
9 × 16² = 2304
3 × 16³ = 12288

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:

10 + 0 + 2304 + 12288 = 14602

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.

14602 ÷ 2 = 7301 with 0 remainder
7301 ÷ 2 = 3650 with 1 remainder
3650 ÷ 2 = 1825 with 0 remainder
1825 ÷ 2 = 912 with 1 remainder
912 ÷ 2 = 456 with 0 remainder
456 ÷ 2 = 228 with 0 remainder
228 ÷ 2 = 114 with 0 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 390A hexadecimal to binary:

390A hexadecimal = 11100100001010 binary
