Given numbers are 129, 183, 774, 665

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

Apply this formula for all numbers.

Step1:

LCM(129, 183) = 7869

GCD(129, 183) = ( 129 x 183 ) / 7869

= 129 / 183

= 129

Step2:

LCM(3, 774) = 774

GCD(3, 774) = ( 3 x 774 ) / 774

= 3 / 774

= 3

Step3:

LCM(3, 665) = 1995

GCD(3, 665) = ( 3 x 665 ) / 1995

= 3 / 665

= 3

So, Greatest Common Divisor of 129, 183, 774, 665 is 1
