7400 octal to binary

Here we will show you how to convert the octal number 7400 to a binary number. First note that the octal number system has eight different digits (0 1 2 3 4 5 6 7) and the binary number system has only two different digits (0 and 1).

The four steps used to convert 7400 from octal to binary are explained below.

Step 1)
Multiply the last digit in 7400 by 8⁰, multiply the second to last digit in 7400 by 8¹, multiply the third to last digit in 7400 by 8², multiply the fourth to last digit in 7400 by 8³, and so on, until all the digits are used:

0 × 8⁰ = 0
0 × 8¹ = 0
4 × 8² = 256
7 × 8³ = 3584

Step 2)
Next, we add up all the products we got from Step 1, like this:

0 + 0 + 256 + 3584 = 3840

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.

3840 ÷ 2 = 1920 with 0 remainder
1920 ÷ 2 = 960 with 0 remainder
960 ÷ 2 = 480 with 0 remainder
480 ÷ 2 = 240 with 0 remainder
240 ÷ 2 = 120 with 0 remainder
120 ÷ 2 = 60 with 0 remainder
60 ÷ 2 = 30 with 0 remainder
30 ÷ 2 = 15 with 0 remainder
15 ÷ 2 = 7 with 1 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 7400 octal to binary:

7400 octal = 111100000000 binary
