Given numbers are 351, 345, 196, 257

The list of prime factors of all numbers are

Prime factors of 351 are 3 x 3 x 3 x 13

Prime factors of 345 are 3 x 5 x 23

Prime factors of 196 are 2 x 2 x 7 x 7

Prime factors of 257 are 257

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

Given numbers are 351, 345, 196, 257

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

Apply this formula for all numbers.

Step1:

LCM(351, 345) = 40365

GCD(351, 345) = ( 351 x 345 ) / 40365

= 351 / 345

= 351

Step2:

LCM(3, 196) = 588

GCD(3, 196) = ( 3 x 196 ) / 588

= 3 / 196

= 3

Step3:

LCM(1, 257) = 257

GCD(1, 257) = ( 1 x 257 ) / 257

= 1 / 257

= 1

So, Greatest Common Divisor of 351, 345, 196, 257 is 1
