GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(618, 938) = 289842
GCD(618, 938) = ( 618 x 938 ) / 289842
= 618 / 938
= 618
Step2:
LCM(2, 789) = 1578
GCD(2, 789) = ( 2 x 789 ) / 1578
= 2 / 789
= 2
Step3:
LCM(1, 731) = 731
GCD(1, 731) = ( 1 x 731 ) / 731
= 1 / 731
= 1
So, Greatest Common Divisor of 618, 938, 789, 731 is 1
