GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(388, 267) = 103596
GCD(388, 267) = ( 388 x 267 ) / 103596
= 388 / 267
= 388
Step2:
LCM(1, 220) = 220
GCD(1, 220) = ( 1 x 220 ) / 220
= 1 / 220
= 1
Step3:
LCM(1, 128) = 128
GCD(1, 128) = ( 1 x 128 ) / 128
= 1 / 128
= 1
So, Greatest Common Divisor of 388, 267, 220, 128 is 1
