Given numbers are 255, 870, 310, 309

The list of prime factors of all numbers are

Prime factors of 255 are 3 x 5 x 17

Prime factors of 870 are 2 x 3 x 5 x 29

Prime factors of 310 are 2 x 5 x 31

Prime factors of 309 are 3 x 103

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

Given numbers are 255, 870, 310, 309

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

Apply this formula for all numbers.

Step1:

LCM(255, 870) = 14790

GCD(255, 870) = ( 255 x 870 ) / 14790

= 255 / 870

= 255

Step2:

LCM(15, 310) = 930

GCD(15, 310) = ( 15 x 310 ) / 930

= 15 / 310

= 15

Step3:

LCM(5, 309) = 1545

GCD(5, 309) = ( 5 x 309 ) / 1545

= 5 / 309

= 5

So, Greatest Common Divisor of 255, 870, 310, 309 is 1
