Given numbers are 710, 645, 813, 129
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(710, 645) = 91590
GCD(710, 645) = ( 710 x 645 ) / 91590
= 710 / 645
= 710
Step2:
LCM(5, 813) = 4065
GCD(5, 813) = ( 5 x 813 ) / 4065
= 5 / 813
= 5
Step3:
LCM(1, 129) = 129
GCD(1, 129) = ( 1 x 129 ) / 129
= 1 / 129
= 1
So, Greatest Common Divisor of 710, 645, 813, 129 is 1
