GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(819, 153) = 13923
GCD(819, 153) = ( 819 x 153 ) / 13923
= 819 / 153
= 819
Step2:
LCM(9, 217) = 1953
GCD(9, 217) = ( 9 x 217 ) / 1953
= 9 / 217
= 9
Step3:
LCM(1, 323) = 323
GCD(1, 323) = ( 1 x 323 ) / 323
= 1 / 323
= 1
So, Greatest Common Divisor of 819, 153, 217, 323 is 1
