GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(419, 388) = 162572
GCD(419, 388) = ( 419 x 388 ) / 162572
= 419 / 388
= 419
Step2:
LCM(1, 868) = 868
GCD(1, 868) = ( 1 x 868 ) / 868
= 1 / 868
= 1
Step3:
LCM(1, 789) = 789
GCD(1, 789) = ( 1 x 789 ) / 789
= 1 / 789
= 1
So, Greatest Common Divisor of 419, 388, 868, 789 is 1
