Convert 269 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 >= 269
80 = 1
81 = 8
82 = 64
83 = 512 <--- Stop: This is greater than 269
Since 512 is greater than 269, 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 269 is 4
Multiplying this coefficient by our original value, we get: 4 * 64 = 256
Add our new value to our running total, we get:
0 + 256 = 256
This is <= 269, so we assign our outside coefficient of 4 for this digit.
Our new sum becomes 256
Our octal notation is now equal to 4
The highest coefficient less than 7 we can multiply this by to stay under 269 is 1
Multiplying this coefficient by our original value, we get: 1 * 8 = 8
Add our new value to our running total, we get:
256 + 8 = 264
This is <= 269, so we assign our outside coefficient of 1 for this digit.
Our new sum becomes 264
Our octal notation is now equal to 41
The highest coefficient less than 7 we can multiply this by to stay under 269 is 5
Multiplying this coefficient by our original value, we get: 5 * 1 = 5
Add our new value to our running total, we get:
264 + 5 = 269
This = 269, so we assign our outside coefficient of 5 for this digit.
Our new sum becomes 269
Our octal notation is now equal to 415
