GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(213, 789) = 56019
GCD(213, 789) = ( 213 x 789 ) / 56019
= 213 / 789
= 213
Step2:
LCM(3, 681) = 681
GCD(3, 681) = ( 3 x 681 ) / 681
= 3 / 681
= 3
Step3:
LCM(3, 991) = 2973
GCD(3, 991) = ( 3 x 991 ) / 2973
= 3 / 991
= 3
So, Greatest Common Divisor of 213, 789, 681, 991 is 1
