Given numbers are 129, 399, 291, 860

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

Apply this formula for all numbers.

Step1:

LCM(129, 399) = 17157

GCD(129, 399) = ( 129 x 399 ) / 17157

= 129 / 399

= 129

Step2:

LCM(3, 291) = 291

GCD(3, 291) = ( 3 x 291 ) / 291

= 3 / 291

= 3

Step3:

LCM(3, 860) = 2580

GCD(3, 860) = ( 3 x 860 ) / 2580

= 3 / 860

= 3

So, Greatest Common Divisor of 129, 399, 291, 860 is 1
