705A hexadecimal to binary

Here we will show you how to convert the hexadecimal number 705A 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 705A from hexadecimal to binary are explained below.

Step 1)
Multiply the last digit in 705A by 16⁰, multiply the second to last digit in 705A by 16¹, multiply the third to last digit in 705A by 16², multiply the fourth to last digit in 705A by 16³, and so on, until all the digits are used.

A × 16⁰ = 10
5 × 16¹ = 80
0 × 16² = 0
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:

10 + 80 + 0 + 28672 = 28762

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.

28762 ÷ 2 = 14381 with 0 remainder
14381 ÷ 2 = 7190 with 1 remainder
7190 ÷ 2 = 3595 with 0 remainder
3595 ÷ 2 = 1797 with 1 remainder
1797 ÷ 2 = 898 with 1 remainder
898 ÷ 2 = 449 with 0 remainder
449 ÷ 2 = 224 with 1 remainder
224 ÷ 2 = 112 with 0 remainder
112 ÷ 2 = 56 with 0 remainder
56 ÷ 2 = 28 with 0 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 705A hexadecimal to binary:

705A hexadecimal = 111000001011010 binary
