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

Apply this formula for all numbers.

Step1:

LCM(819, 342) = 31122

GCD(819, 342) = ( 819 x 342 ) / 31122

= 819 / 342

= 819

Step2:

LCM(9, 987) = 2961

GCD(9, 987) = ( 9 x 987 ) / 2961

= 9 / 987

= 9

Step3:

LCM(3, 171) = 171

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

= 3 / 171

= 3

So, Greatest Common Divisor of 819, 342, 987, 171 is 3
