Given numbers are 354, 178, 256, 431

The list of prime factors of all numbers are

Prime factors of 354 are 2 x 3 x 59

Prime factors of 178 are 2 x 89

Prime factors of 256 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime factors of 431 are 431

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

Given numbers are 354, 178, 256, 431

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

Apply this formula for all numbers.

Step1:

LCM(354, 178) = 31506

GCD(354, 178) = ( 354 x 178 ) / 31506

= 354 / 178

= 354

Step2:

LCM(2, 256) = 256

GCD(2, 256) = ( 2 x 256 ) / 256

= 2 / 256

= 2

Step3:

LCM(2, 431) = 862

GCD(2, 431) = ( 2 x 431 ) / 862

= 2 / 431

= 2

So, Greatest Common Divisor of 354, 178, 256, 431 is 1
