Convert 227 from decimal to octal

(base 8) notation:

Power Test

Raise our base of 8 to a power

Start at 0 and increasing by 1 until it is >= 227

8⁰ = 1

8¹ = 8

8² = 64

8³ = 512 <--- Stop: This is greater than 227

Since 512 is greater than 227, we use 1 power less as our starting point which equals 2

Build octal notation

Work backwards from a power of 2

We start with a total sum of 0:

8² = 64

The highest coefficient less than 7 we can multiply this by to stay under 227 is 3

Multiplying this coefficient by our original value, we get: 3 * 64 = 192

Add our new value to our running total, we get:
0 + 192 = 192

This is <= 227, so we assign our outside coefficient of 3 for this digit.

Our new sum becomes 192

Our octal notation is now equal to 3

8¹ = 8

The highest coefficient less than 7 we can multiply this by to stay under 227 is 4

Multiplying this coefficient by our original value, we get: 4 * 8 = 32

Add our new value to our running total, we get:
192 + 32 = 224

This is <= 227, so we assign our outside coefficient of 4 for this digit.

Our new sum becomes 224

Our octal notation is now equal to 34

8⁰ = 1

The highest coefficient less than 7 we can multiply this by to stay under 227 is 3

Multiplying this coefficient by our original value, we get: 3 * 1 = 3

Add our new value to our running total, we get:
224 + 3 = 227

This = 227, so we assign our outside coefficient of 3 for this digit.

Our new sum becomes 227

Our octal notation is now equal to 343
