GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(819, 585) = 4095
GCD(819, 585) = ( 819 x 585 ) / 4095
= 819 / 585
= 819
Step2:
LCM(117, 196) = 22932
GCD(117, 196) = ( 117 x 196 ) / 22932
= 117 / 196
= 117
Step3:
LCM(1, 409) = 409
GCD(1, 409) = ( 1 x 409 ) / 409
= 1 / 409
= 1
So, Greatest Common Divisor of 819, 585, 196, 409 is 1
