139A hexadecimal to binary

Here we will show you how to convert the hexadecimal number 139A 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 139A from hexadecimal to binary are explained below.

Step 1)
Multiply the last digit in 139A by 16⁰, multiply the second to last digit in 139A by 16¹, multiply the third to last digit in 139A by 16², multiply the fourth to last digit in 139A by 16³, and so on, until all the digits are used.

A × 16⁰ = 10
9 × 16¹ = 144
3 × 16² = 768
1 × 16³ = 4096

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 + 144 + 768 + 4096 = 5018

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.

5018 ÷ 2 = 2509 with 0 remainder
2509 ÷ 2 = 1254 with 1 remainder
1254 ÷ 2 = 627 with 0 remainder
627 ÷ 2 = 313 with 1 remainder
313 ÷ 2 = 156 with 1 remainder
156 ÷ 2 = 78 with 0 remainder
78 ÷ 2 = 39 with 0 remainder
39 ÷ 2 = 19 with 1 remainder
19 ÷ 2 = 9 with 1 remainder
9 ÷ 2 = 4 with 1 remainder
4 ÷ 2 = 2 with 0 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 139A hexadecimal to binary:

139A hexadecimal = 1001110011010 binary
