Given numbers are 171, 198, 389, 516

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

Apply this formula for all numbers.

Step1:

LCM(171, 198) = 3762

GCD(171, 198) = ( 171 x 198 ) / 3762

= 171 / 198

= 171

Step2:

LCM(9, 389) = 3501

GCD(9, 389) = ( 9 x 389 ) / 3501

= 9 / 389

= 9

Step3:

LCM(1, 516) = 516

GCD(1, 516) = ( 1 x 516 ) / 516

= 1 / 516

= 1

So, Greatest Common Divisor of 171, 198, 389, 516 is 1
