Given numbers are 128, 254, 256

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(128, 254) = 16256

GCD(128, 254) = ( 128 x 254 ) / 16256

= 128 / 254

= 128

Step2:

LCM(2, 256) = 256

GCD(2, 256) = ( 2 x 256 ) / 256

= 2 / 256

= 2

So, Greatest Common Divisor of 128, 254, 256 is 2
