Question

Convert the following 689 into octal​

Answer 1

Answer:

1261

explanation:

Step 1) Divide 689 by 8 to get the Quotient. Keep the Whole part for the next step and set the Remainder aside.

Step 2) Divide the Whole part of the Quotient from step 1 by 8. Again keep the Whole part and set the Remainder aside.

Step 3) Repeat Step 2 above until the Whole part is 0.

Step 4) Write down the Remainders in reverse order to get the answer to 689 as an octal.

Here we will show our work so you can follow along:

689 / 8 = 86 with 1 remainder

86 / 8 = 10 with 6 remainder

10 / 8 = 1 with 2 remainder

1 / 8 = 0 with 1 remainder

Then, when we put the remainders together in reverse order, we get the answer. The decimal number 689 converted to octal is therefore:

1261
