GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(819, 735) = 28665

GCD(819, 735) = ( 819 x 735 ) / 28665

= 819 / 735

= 819

Step2:

LCM(21, 570) = 3990

GCD(21, 570) = ( 21 x 570 ) / 3990

= 21 / 570

= 21

Step3:

LCM(3, 171) = 171

GCD(3, 171) = ( 3 x 171 ) / 171

= 3 / 171

= 3

So, Greatest Common Divisor of 819, 735, 570, 171 is 3
