Given numbers are 129, 291, 515, 459

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

Apply this formula for all numbers.

Step1:

LCM(129, 291) = 12513

GCD(129, 291) = ( 129 x 291 ) / 12513

= 129 / 291

= 129

Step2:

LCM(3, 515) = 1545

GCD(3, 515) = ( 3 x 515 ) / 1545

= 3 / 515

= 3

Step3:

LCM(1, 459) = 459

GCD(1, 459) = ( 1 x 459 ) / 459

= 1 / 459

= 1

So, Greatest Common Divisor of 129, 291, 515, 459 is 1
