Convert 279 from decimal to hexadecimal

(base 16) notation:

Power Test

Raise our base of 16 to a power

Start at 0 and increasing by 1 until it is >= 279

16⁰ = 1

16¹ = 16

16² = 256

16³ = 4096 <--- Stop: This is greater than 279

Since 4096 is greater than 279, we use 1 power less as our starting point which equals 2

Build hexadecimal notation

Work backwards from a power of 2

We start with a total sum of 0:

16² = 256

The highest coefficient less than 15 we can multiply this by to stay under 279 is 1

Multiplying this coefficient by our original value, we get: 1 * 256 = 256

Add our new value to our running total, we get:
0 + 256 = 256

This is <= 279, so we assign our outside coefficient of 1 for this digit.

Our new sum becomes 256

Our hexadecimal notation is now equal to 1

16¹ = 16

The highest coefficient less than 15 we can multiply this by to stay under 279 is 1

Multiplying this coefficient by our original value, we get: 1 * 16 = 16

Add our new value to our running total, we get:
256 + 16 = 272

This is <= 279, so we assign our outside coefficient of 1 for this digit.

Our new sum becomes 272

Our hexadecimal notation is now equal to 11

16⁰ = 1

The highest coefficient less than 15 we can multiply this by to stay under 279 is 7

Multiplying this coefficient by our original value, we get: 7 * 1 = 7

Add our new value to our running total, we get:
272 + 7 = 279

This = 279, so we assign our outside coefficient of 7 for this digit.

Our new sum becomes 279

Our hexadecimal notation is now equal to 117
