Given numbers are 217, 187, 159, 819

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

Apply this formula for all numbers.

Step1:

LCM(217, 187) = 40579

GCD(217, 187) = ( 217 x 187 ) / 40579

= 217 / 187

= 217

Step2:

LCM(1, 159) = 159

GCD(1, 159) = ( 1 x 159 ) / 159

= 1 / 159

= 1

Step3:

LCM(1, 819) = 819

GCD(1, 819) = ( 1 x 819 ) / 819

= 1 / 819

= 1

So, Greatest Common Divisor of 217, 187, 159, 819 is 1
