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

Apply this formula for all numbers.

Step1:

LCM(402, 128) = 25728

GCD(402, 128) = ( 402 x 128 ) / 25728

= 402 / 128

= 402

Step2:

LCM(2, 192) = 192

GCD(2, 192) = ( 2 x 192 ) / 192

= 2 / 192

= 2

Step3:

LCM(2, 388) = 388

GCD(2, 388) = ( 2 x 388 ) / 388

= 2 / 388

= 2

So, Greatest Common Divisor of 402, 128, 192, 388 is 2
