GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(778, 689) = 536042
GCD(778, 689) = ( 778 x 689 ) / 536042
= 778 / 689
= 778
Step2:
LCM(1, 893) = 893
GCD(1, 893) = ( 1 x 893 ) / 893
= 1 / 893
= 1
Step3:
LCM(1, 789) = 789
GCD(1, 789) = ( 1 x 789 ) / 789
= 1 / 789
= 1
So, Greatest Common Divisor of 778, 689, 893, 789 is 1
