GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(478, 334) = 79826
GCD(478, 334) = ( 478 x 334 ) / 79826
= 478 / 334
= 478
Step2:
LCM(2, 18) = 18
GCD(2, 18) = ( 2 x 18 ) / 18
= 2 / 18
= 2
Step3:
LCM(2, 128) = 128
GCD(2, 128) = ( 2 x 128 ) / 128
= 2 / 128
= 2
So, Greatest Common Divisor of 478, 334, 18, 128 is 2
