GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(729, 195) = 47385
GCD(729, 195) = ( 729 x 195 ) / 47385
= 729 / 195
= 729
Step2:
LCM(3, 853) = 2559
GCD(3, 853) = ( 3 x 853 ) / 2559
= 3 / 853
= 3
Step3:
LCM(1, 630) = 630
GCD(1, 630) = ( 1 x 630 ) / 630
= 1 / 630
= 1
So, Greatest Common Divisor of 729, 195, 853, 630 is 1
