Given numbers are 509, 989, 191, 668

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

Apply this formula for all numbers.

Step1:

LCM(509, 989) = 503401

GCD(509, 989) = ( 509 x 989 ) / 503401

= 509 / 989

= 509

Step2:

LCM(1, 191) = 191

GCD(1, 191) = ( 1 x 191 ) / 191

= 1 / 191

= 1

Step3:

LCM(1, 668) = 668

GCD(1, 668) = ( 1 x 668 ) / 668

= 1 / 668

= 1

So, Greatest Common Divisor of 509, 989, 191, 668 is 1
