Convert 299 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 >= 299

8⁰ = 1

8¹ = 8

8² = 64

8³ = 512 <--- Stop: This is greater than 299

Since 512 is greater than 299, 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 299 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 <= 299, so we assign our outside coefficient of 4 for this digit.

Our new sum becomes 256

Our octal notation is now equal to 4

8¹ = 8

The highest coefficient less than 7 we can multiply this by to stay under 299 is 5

Multiplying this coefficient by our original value, we get: 5 * 8 = 40

Add our new value to our running total, we get:
256 + 40 = 296

This is <= 299, so we assign our outside coefficient of 5 for this digit.

Our new sum becomes 296

Our octal notation is now equal to 45

8⁰ = 1

The highest coefficient less than 7 we can multiply this by to stay under 299 is 3

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

Add our new value to our running total, we get:
296 + 3 = 299

This = 299, so we assign our outside coefficient of 3 for this digit.

Our new sum becomes 299

Our octal notation is now equal to 453
