Given numbers are 634, 558, 388, 789
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(634, 558) = 176886
GCD(634, 558) = ( 634 x 558 ) / 176886
= 634 / 558
= 634
Step2:
LCM(2, 388) = 388
GCD(2, 388) = ( 2 x 388 ) / 388
= 2 / 388
= 2
Step3:
LCM(2, 789) = 1578
GCD(2, 789) = ( 2 x 789 ) / 1578
= 2 / 789
= 2
So, Greatest Common Divisor of 634, 558, 388, 789 is 1
