Given numbers are 129, 714, 770, 819
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(129, 714) = 30702
GCD(129, 714) = ( 129 x 714 ) / 30702
= 129 / 714
= 129
Step2:
LCM(3, 770) = 2310
GCD(3, 770) = ( 3 x 770 ) / 2310
= 3 / 770
= 3
Step3:
LCM(1, 819) = 819
GCD(1, 819) = ( 1 x 819 ) / 819
= 1 / 819
= 1
So, Greatest Common Divisor of 129, 714, 770, 819 is 1
