Given numbers are 205, 509, 793, 430

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

Apply this formula for all numbers.

Step1:

LCM(205, 509) = 104345

GCD(205, 509) = ( 205 x 509 ) / 104345

= 205 / 509

= 205

Step2:

LCM(1, 793) = 793

GCD(1, 793) = ( 1 x 793 ) / 793

= 1 / 793

= 1

Step3:

LCM(1, 430) = 430

GCD(1, 430) = ( 1 x 430 ) / 430

= 1 / 430

= 1

So, Greatest Common Divisor of 205, 509, 793, 430 is 1
