124 is the octal number

Step 1: Write down the binary number

(001010100)

Group all the digits in sets of three starting from the LSB (far right). Add zeros to the left of the last digit if there aren't enough digits to make a set of three.

001 010 100

Step 2: Use the table below to convert each set of three into an octal digit. In this case,

001=1, 010=2, 100=4.

So, the number 124 is the octal equivalent to 1010100 in binary.
