GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(164, 789) = 129396
GCD(164, 789) = ( 164 x 789 ) / 129396
= 164 / 789
= 164
Step2:
LCM(1, 686) = 686
GCD(1, 686) = ( 1 x 686 ) / 686
= 1 / 686
= 1
Step3:
LCM(1, 242) = 242
GCD(1, 242) = ( 1 x 242 ) / 242
= 1 / 242
= 1
So, Greatest Common Divisor of 164, 789, 686, 242 is 1
