GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(658, 378) = 17766
GCD(658, 378) = ( 658 x 378 ) / 17766
= 658 / 378
= 658
Step2:
LCM(14, 866) = 6062
GCD(14, 866) = ( 14 x 866 ) / 6062
= 14 / 866
= 14
Step3:
LCM(2, 343) = 686
GCD(2, 343) = ( 2 x 343 ) / 686
= 2 / 343
= 2
So, Greatest Common Divisor of 658, 378, 866, 343 is 1
