Given numbers are 388, 764, 129, 618
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(388, 764) = 74108
GCD(388, 764) = ( 388 x 764 ) / 74108
= 388 / 764
= 388
Step2:
LCM(4, 129) = 516
GCD(4, 129) = ( 4 x 129 ) / 516
= 4 / 129
= 4
Step3:
LCM(1, 618) = 618
GCD(1, 618) = ( 1 x 618 ) / 618
= 1 / 618
= 1
So, Greatest Common Divisor of 388, 764, 129, 618 is 1
