GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(812, 686) = 39788
GCD(812, 686) = ( 812 x 686 ) / 39788
= 812 / 686
= 812
Step2:
LCM(14, 418) = 2926
GCD(14, 418) = ( 14 x 418 ) / 2926
= 14 / 418
= 14
Step3:
LCM(2, 954) = 954
GCD(2, 954) = ( 2 x 954 ) / 954
= 2 / 954
= 2
So, Greatest Common Divisor of 812, 686, 418, 954 is 2
