GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 884) = 281996
GCD(638, 884) = ( 638 x 884 ) / 281996
= 638 / 884
= 638
Step2:
LCM(2, 568) = 568
GCD(2, 568) = ( 2 x 568 ) / 568
= 2 / 568
= 2
Step3:
LCM(2, 789) = 1578
GCD(2, 789) = ( 2 x 789 ) / 1578
= 2 / 789
= 2
So, Greatest Common Divisor of 638, 884, 568, 789 is 1
