GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(686, 798) = 39102
GCD(686, 798) = ( 686 x 798 ) / 39102
= 686 / 798
= 686
Step2:
LCM(14, 928) = 6496
GCD(14, 928) = ( 14 x 928 ) / 6496
= 14 / 928
= 14
Step3:
LCM(2, 354) = 354
GCD(2, 354) = ( 2 x 354 ) / 354
= 2 / 354
= 2
So, Greatest Common Divisor of 686, 798, 928, 354 is 2
