The list of prime factors of all numbers are

Prime factors of 438 are 2 x 3 x 73

Prime factors of 129 are 3 x 43

Prime factors of 518 are 2 x 7 x 37

Prime factors of 785 are 5 x 157

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

Given numbers are 438, 129, 518, 785

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

Apply this formula for all numbers.

Step1:

LCM(438, 129) = 18834

GCD(438, 129) = ( 438 x 129 ) / 18834

= 438 / 129

= 438

Step2:

LCM(3, 518) = 1554

GCD(3, 518) = ( 3 x 518 ) / 1554

= 3 / 518

= 3

Step3:

LCM(1, 785) = 785

GCD(1, 785) = ( 1 x 785 ) / 785

= 1 / 785

= 1

So, Greatest Common Divisor of 438, 129, 518, 785 is 1
