Given numbers are 438, 758, 857, 345

The list of prime factors of all numbers are

Prime factors of 438 are 2 x 3 x 73

Prime factors of 758 are 2 x 379

Prime factors of 857 are 857

Prime factors of 345 are 3 x 5 x 23

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

Given numbers are 438, 758, 857, 345

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

Apply this formula for all numbers.

Step1:

LCM(438, 758) = 166002

GCD(438, 758) = ( 438 x 758 ) / 166002

= 438 / 758

= 438

Step2:

LCM(2, 857) = 1714

GCD(2, 857) = ( 2 x 857 ) / 1714

= 2 / 857

= 2

Step3:

LCM(1, 345) = 345

GCD(1, 345) = ( 1 x 345 ) / 345

= 1 / 345

= 1

So, Greatest Common Divisor of 438, 758, 857, 345 is 1
