Given numbers are 255, 645, 298, 342

The list of prime factors of all numbers are

Prime factors of 255 are 3 x 5 x 17

Prime factors of 645 are 3 x 5 x 43

Prime factors of 298 are 2 x 149

Prime factors of 342 are 2 x 3 x 3 x 19

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

Given numbers are 255, 645, 298, 342

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

Apply this formula for all numbers.

Step1:

LCM(255, 645) = 10965

GCD(255, 645) = ( 255 x 645 ) / 10965

= 255 / 645

= 255

Step2:

LCM(15, 298) = 4470

GCD(15, 298) = ( 15 x 298 ) / 4470

= 15 / 298

= 15

Step3:

LCM(1, 342) = 342

GCD(1, 342) = ( 1 x 342 ) / 342

= 1 / 342

= 1

So, Greatest Common Divisor of 255, 645, 298, 342 is 1
