Convert 270 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 >= 270

80 = 1

81 = 8

82 = 64

83 = 512 <--- Stop: This is greater than 270

Since 512 is greater than 270, 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 270 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 <= 270, 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 270 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 <= 270, so we assign our outside coefficient of 1 for this digit.

Our new sum becomes 264

Our octal notation is now equal to 41


80 = 1

The highest coefficient less than 7 we can multiply this by to stay under 270 is 6

Multiplying this coefficient by our original value, we get: 6 * 1 = 6

Add our new value to our running total, we get:
264 + 6 = 270

This = 270, so we assign our outside coefficient of 6 for this digit.

Our new sum becomes 270

Our octal notation is now equal to 416


Final Answer

We are done. 270 converted from decimal to octal notation equals 4168.
