Given numbers are 129, 138, 294, 457

The list of prime factors of all numbers are

Prime factors of 129 are 3 x 43

Prime factors of 138 are 2 x 3 x 23

Prime factors of 294 are 2 x 3 x 7 x 7

Prime factors of 457 are 457

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 129, 138, 294, 457

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

Apply this formula for all numbers.

Step1:

LCM(129, 138) = 5934

GCD(129, 138) = ( 129 x 138 ) / 5934

= 129 / 138

= 129

Step2:

LCM(3, 294) = 294

GCD(3, 294) = ( 3 x 294 ) / 294

= 3 / 294

= 3

Step3:

LCM(3, 457) = 1371

GCD(3, 457) = ( 3 x 457 ) / 1371

= 3 / 457

= 3

So, Greatest Common Divisor of 129, 138, 294, 457 is 1
