Given numbers are 129, 171, 130, 742

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

Apply this formula for all numbers.

Step1:

LCM(129, 171) = 7353

GCD(129, 171) = ( 129 x 171 ) / 7353

= 129 / 171

= 129

Step2:

LCM(3, 130) = 390

GCD(3, 130) = ( 3 x 130 ) / 390

= 3 / 130

= 3

Step3:

LCM(1, 742) = 742

GCD(1, 742) = ( 1 x 742 ) / 742

= 1 / 742

= 1

So, Greatest Common Divisor of 129, 171, 130, 742 is 1
