GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(819, 645) = 176085
GCD(819, 645) = ( 819 x 645 ) / 176085
= 819 / 645
= 819
Step2:
LCM(3, 198) = 198
GCD(3, 198) = ( 3 x 198 ) / 198
= 3 / 198
= 3
Step3:
LCM(3, 739) = 2217
GCD(3, 739) = ( 3 x 739 ) / 2217
= 3 / 739
= 3
So, Greatest Common Divisor of 819, 645, 198, 739 is 1
