GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(681, 108) = 24516
GCD(681, 108) = ( 681 x 108 ) / 24516
= 681 / 108
= 681
Step2:
LCM(3, 855) = 855
GCD(3, 855) = ( 3 x 855 ) / 855
= 3 / 855
= 3
Step3:
LCM(3, 966) = 966
GCD(3, 966) = ( 3 x 966 ) / 966
= 3 / 966
= 3
So, Greatest Common Divisor of 681, 108, 855, 966 is 3
