74402 octal to binary

Here we will show you how to convert the octal number 74402 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 74402 from octal to binary are explained below.

Step 1)
Multiply the last digit in 74402 by 8⁰, multiply the second to last digit in 74402 by 8¹, multiply the third to last digit in 74402 by 8², multiply the fourth to last digit in 74402 by 8³, and so on, until all the digits are used:

2 × 8⁰ = 2
0 × 8¹ = 0
4 × 8² = 256
4 × 8³ = 2048
7 × 8⁴ = 28672

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

2 + 0 + 256 + 2048 + 28672 = 30978

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.

30978 ÷ 2 = 15489 with 0 remainder
15489 ÷ 2 = 7744 with 1 remainder
7744 ÷ 2 = 3872 with 0 remainder
3872 ÷ 2 = 1936 with 0 remainder
1936 ÷ 2 = 968 with 0 remainder
968 ÷ 2 = 484 with 0 remainder
484 ÷ 2 = 242 with 0 remainder
242 ÷ 2 = 121 with 0 remainder
121 ÷ 2 = 60 with 1 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 74402 octal to binary:

74402 octal = 111100100000010 binary
