Important Notes: (42)10 in Octal
The below are some of the important notes to be remembered while converting the (base-10) decimal number 42 into a (base-8) octal equivalent.
- The first remainder while performing 42 MOD-8 operation is a Least Significant Bit (LSB).
- The final remainder while performing 42 MOD-8 operation is a Most Significant Bit (MSB).
- The remainders of 42 MOD-8 operation should be written from MSB to LSB to form the octal equivalent for the given decimal number (42)10.
How-to: What is (42)10 in octal?
The below step-by-step solution shows how to convert the decimal number 42 to its equivalent octal number. Representing each remainders of 42 MOD-8 operation in octal equivalents and arranging them from MSB to LSB produces the octal equivalent of 42.Solved Example:
What is the octal equivalent of 42?
step 1 Observe the input parameters, values and what to be found:
Decimal Number = (42)10
What to be found:
What is the octal equivalent of the decimal number (42)10?
(42)10 = (?)8
step 2 Perform successive 42 MOD-8 operation until the quotient becomes 0, and mark the first remainder as LSB and the final remainder as MSB as like the below:
Successive MOD-8 Operation for 42
|42 MOD-8||42 / 8 = 5||Remainder is 2 → LSB|
|5 MOD-8||5 / 8 = 0||Remainder is 5 → MSB|
step 3 Arrange or write the remainders of 42 MOD-8 operation from MSB to LSB produces the equivalent octal number for decimal 42:
(42)10 = (52)8
the octal equivalent of decimal 42 is (52)8.
