Given numbers are 129, 687, 259, 666

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

Apply this formula for all numbers.

Step1:

LCM(129, 687) = 29541

GCD(129, 687) = ( 129 x 687 ) / 29541

= 129 / 687

= 129

Step2:

LCM(3, 259) = 777

GCD(3, 259) = ( 3 x 259 ) / 777

= 3 / 259

= 3

Step3:

LCM(1, 666) = 666

GCD(1, 666) = ( 1 x 666 ) / 666

= 1 / 666

= 1

So, Greatest Common Divisor of 129, 687, 259, 666 is 1
