Convert 168 from decimal to octal
(base 8) notation:
Raise our base of 8 to a power
Start at 0 and increasing by 1 until it is >= 168
80 = 1
81 = 8
82 = 64
83 = 512 <--- Stop: This is greater than 168
Since 512 is greater than 168, we use 1 power less as our starting point which equals 2
Work backwards from a power of 2
We start with a total sum of 0:
The highest coefficient less than 7 we can multiply this by to stay under 168 is 2
Multiplying this coefficient by our original value, we get: 2 * 64 = 128
Add our new value to our running total, we get:
0 + 128 = 128
This is <= 168, so we assign our outside coefficient of 2 for this digit.
Our new sum becomes 128
Our octal notation is now equal to 2
The highest coefficient less than 7 we can multiply this by to stay under 168 is 5
Multiplying this coefficient by our original value, we get: 5 * 8 = 40
Add our new value to our running total, we get:
128 + 40 = 168
This = 168, so we assign our outside coefficient of 5 for this digit.
Our new sum becomes 168
Our octal notation is now equal to 25
The highest coefficient less than 7 we can multiply this by to stay under 168 is 1
Multiplying this coefficient by our original value, we get: 1 * 1 = 1
Add our new value to our running total, we get:
168 + 1 = 169
This is > 168, so we assign a 0 for this digit.
Our total sum remains the same at 168
Our octal notation is now equal to 250
