The list of prime factors of all numbers are

Prime factors of 255 are 3 x 5 x 17

Prime factors of 513 are 3 x 3 x 3 x 19

Prime factors of 815 are 5 x 163

Prime factors of 694 are 2 x 347

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

Given numbers are 255, 513, 815, 694

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

Apply this formula for all numbers.

Step1:

LCM(255, 513) = 43605

GCD(255, 513) = ( 255 x 513 ) / 43605

= 255 / 513

= 255

Step2:

LCM(3, 815) = 2445

GCD(3, 815) = ( 3 x 815 ) / 2445

= 3 / 815

= 3

Step3:

LCM(1, 694) = 694

GCD(1, 694) = ( 1 x 694 ) / 694

= 1 / 694

= 1

So, Greatest Common Divisor of 255, 513, 815, 694 is 1
