77A hexadecimal to binary

Here we will show you how to convert the hexadecimal number 77A 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 77A from hexadecimal to binary are explained below.

Step 1)
Multiply the last digit in 77A by 16⁰, multiply the second to last digit in 77A by 16¹, multiply the third to last digit in 77A by 16², multiply the fourth to last digit in 77A by 16³, and so on, until all the digits are used.

A × 16⁰ = 10
7 × 16¹ = 112
7 × 16² = 1792

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 + 112 + 1792 = 1914

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.

1914 ÷ 2 = 957 with 0 remainder
957 ÷ 2 = 478 with 1 remainder
478 ÷ 2 = 239 with 0 remainder
239 ÷ 2 = 119 with 1 remainder
119 ÷ 2 = 59 with 1 remainder
59 ÷ 2 = 29 with 1 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 77A hexadecimal to binary:

77A hexadecimal = 11101111010 binary
