Given numbers are 255, 610, 209, 428

The list of prime factors of all numbers are

Prime factors of 255 are 3 x 5 x 17

Prime factors of 610 are 2 x 5 x 61

Prime factors of 209 are 11 x 19

Prime factors of 428 are 2 x 2 x 107

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

Given numbers are 255, 610, 209, 428

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

Apply this formula for all numbers.

Step1:

LCM(255, 610) = 31110

GCD(255, 610) = ( 255 x 610 ) / 31110

= 255 / 610

= 255

Step2:

LCM(5, 209) = 1045

GCD(5, 209) = ( 5 x 209 ) / 1045

= 5 / 209

= 5

Step3:

LCM(1, 428) = 428

GCD(1, 428) = ( 1 x 428 ) / 428

= 1 / 428

= 1

So, Greatest Common Divisor of 255, 610, 209, 428 is 1
