The list of prime factors of all numbers are

Prime factors of 718 are 2 x 359

Prime factors of 476 are 2 x 2 x 7 x 17

Prime factors of 645 are 3 x 5 x 43

Prime factors of 129 are 3 x 43

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

Given numbers are 718, 476, 645, 129

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

Apply this formula for all numbers.

Step1:

LCM(718, 476) = 170884

GCD(718, 476) = ( 718 x 476 ) / 170884

= 718 / 476

= 718

Step2:

LCM(2, 645) = 1290

GCD(2, 645) = ( 2 x 645 ) / 1290

= 2 / 645

= 2

Step3:

LCM(1, 129) = 129

GCD(1, 129) = ( 1 x 129 ) / 129

= 1 / 129

= 1

So, Greatest Common Divisor of 718, 476, 645, 129 is 1
