Given numbers are 128, 136, 488, 378

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

Apply this formula for all numbers.

Step1:

LCM(128, 136) = 2176

GCD(128, 136) = ( 128 x 136 ) / 2176

= 128 / 136

= 128

Step2:

LCM(8, 488) = 488

GCD(8, 488) = ( 8 x 488 ) / 488

= 8 / 488

= 8

Step3:

LCM(8, 378) = 1512

GCD(8, 378) = ( 8 x 378 ) / 1512

= 8 / 378

= 8

So, Greatest Common Divisor of 128, 136, 488, 378 is 2
