Given numbers are 255, 347, 342, 810

The list of prime factors of all numbers are

Prime factors of 255 are 3 x 5 x 17

Prime factors of 347 are 347

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

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

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

Given numbers are 255, 347, 342, 810

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

Apply this formula for all numbers.

Step1:

LCM(255, 347) = 88485

GCD(255, 347) = ( 255 x 347 ) / 88485

= 255 / 347

= 255

Step2:

LCM(1, 342) = 342

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

= 1 / 342

= 1

Step3:

LCM(1, 810) = 810

GCD(1, 810) = ( 1 x 810 ) / 810

= 1 / 810

= 1

So, Greatest Common Divisor of 255, 347, 342, 810 is 1
