Given numbers are 255, 306, 717, 290

The list of prime factors of all numbers are

Prime factors of 255 are 3 x 5 x 17

Prime factors of 306 are 2 x 3 x 3 x 17

Prime factors of 717 are 3 x 239

Prime factors of 290 are 2 x 5 x 29

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

Given numbers are 255, 306, 717, 290

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

Apply this formula for all numbers.

Step1:

LCM(255, 306) = 1530

GCD(255, 306) = ( 255 x 306 ) / 1530

= 255 / 306

= 255

Step2:

LCM(51, 717) = 12189

GCD(51, 717) = ( 51 x 717 ) / 12189

= 51 / 717

= 51

Step3:

LCM(3, 290) = 870

GCD(3, 290) = ( 3 x 290 ) / 870

= 3 / 290

= 3

So, Greatest Common Divisor of 255, 306, 717, 290 is 1
