74342 octal to binary

Here we will show you how to convert the octal number 74342 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 74342 from octal to binary are explained below.

Step 1)
Multiply the last digit in 74342 by 8⁰, multiply the second to last digit in 74342 by 8¹, multiply the third to last digit in 74342 by 8², multiply the fourth to last digit in 74342 by 8³, and so on, until all the digits are used:

2 × 8⁰ = 2
4 × 8¹ = 32
3 × 8² = 192
4 × 8³ = 2048
7 × 8⁴ = 28672

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

2 + 32 + 192 + 2048 + 28672 = 30946

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.

30946 ÷ 2 = 15473 with 0 remainder
15473 ÷ 2 = 7736 with 1 remainder
7736 ÷ 2 = 3868 with 0 remainder
3868 ÷ 2 = 1934 with 0 remainder
1934 ÷ 2 = 967 with 0 remainder
967 ÷ 2 = 483 with 1 remainder
483 ÷ 2 = 241 with 1 remainder
241 ÷ 2 = 120 with 1 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 74342 octal to binary:

74342 octal = 111100011100010 binary
