Given numbers are 388, 384, 440, 428

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

Apply this formula for all numbers.

Step1:

LCM(388, 384) = 37248

GCD(388, 384) = ( 388 x 384 ) / 37248

= 388 / 384

= 388

Step2:

LCM(4, 440) = 440

GCD(4, 440) = ( 4 x 440 ) / 440

= 4 / 440

= 4

Step3:

LCM(4, 428) = 428

GCD(4, 428) = ( 4 x 428 ) / 428

= 4 / 428

= 4

So, Greatest Common Divisor of 388, 384, 440, 428 is 4
